Nomads, the NON settler. I never used to get these guys, except maybe late in the game in some remote location. But in the last three games I've played I've tipped them out of huts in bunches. Before that, I always had my original NON settler working on my capital grounds. But in the last few games I've founded two cities to start -- and lo, the Nomads came forth in multitudes. Well actually, I think you only get one until you found a city with it, then you can get another one.
I decided to test this out. I started on a map with all forest squares, founded my first city, created a slew of explorers and started tipping huts. I kept my original NON settler and out of 50 huts, found not one Nomad. Tried again, this time with two cities, and I got 13 Nomads out of 50 huts (each time disbanding the settler). Several times, more than coincidence I think, I got 2 Nomads in a row. (Other kinds of results came mostly in twos also.) After awhile I thought I noticed a relationship between the hut's location (and position in the hut pattern) and the result of the tip. Has anyone explored this before? Is there a relationship? Can hut results be predicted?

Not necessarily.
I'm not saying there's no random element to it, merely that it's not completely random.
An algorythm may include randomness, yet also have predictable logic elements as well.
Some of these are already known. Perhaps there are others to be discovered.
The save/restore causing different results is clearly designed to frustrate predictabity,
but is the design itself truly random? I'm not so sure.
Has anyone tried to crack this? Does anyone have ideas on setting up test cases
that might flush out more of the pattern, if there is one, or prove that none exists?

ok i tested my SP theory about coming at hutsfrom different angles.........
I created three units and had them all pop the same hut.......
the first unit always popped an archer......
the second unit popped up money and various units..
the third unit popped up money and various units.... however after the 10th try everything was archers......
i got one chariot and two horses.........
it seemed to go in turns too...... ie archer, 50g, horse, archer, 25g, chariot, archer, 25g, horse, archer, archer , archer,
now this was done with two cities side by side and built on this turn. Part of my testing has led me to believe that nomads are one per small land mass. However this is false as last night in an mp game i got a nomad from a hut one a mountain and three turns later i got another one from a mountain....i used the nomad to tip the hut too........and its not the first time this has happened.
nomads are unlimited on the poles as well
now my testing didnt give any nomads as the hut was right beside a city...... however i need to test this theory in open territory.......sorry this is rambled........

War,
Thanks much.
I tried incorporating your direction idea with my pattern testing idea.
I popped another 50 huts, always from the same direction and always taking the same path through the hut pattern.
This was done after founding two cities to eliminate my NON settlers, all huts were on forest to allow the possibility of Nomads.
The results:
24 nomads, 20 mercenaries, 3 barbs, 1 gold, 2 wisdom.
That's not randomness.
The gold came from a hut that I had to approach from a different direction because of water. The 2 wisdoms came from a break in the hut pattern. Most of the time I got N,M,N,M ... but I also had a lot of two Nomad strings and a couple of threes.
Each time I received a Nomad I disbanded it. I think this is one of the events that triggers something, maybe re-seeds the generator. Like founding a first city or discovering Invention, ridding yourself of your NON settler restarts the sequence, maybe.
You can found a city, disband the unit, or home it to a city. Same effect -- your chance of getting a Nomad goes way up; approaching 50% in this test case.
Obviously, more work needs to be done here. But at this point it would be tough to convince me
there is not an exploitable mechanism at work.

I have suspected for a long time now that there is a sequence to hut outcomes. That is based purely on gameplay experience, however, not one ounce of testing.
The notion that the angle from which the tip is made influences outcome is new to me. It is intriguing. Rib had a theory (which I liked the look of but later discarded) that clearing away the fog of war reduced the likelihood of barbs. While I am now fairly sure this is not true of itself it strikes me that what her technique may have resulted in is a distortion to the angle from which she tipped (more North to South when her starting location was Southerly etc.).
The high incidence of nomads which you have discovered is surprising and seems to me highly significant. I have often taken a NONE settler back to my heartlands in order to use him for land improvement. While there remain plenty of forest/hills/mountain huts to tip that is now exposed as poor tactics. In such cases prompt founding is called for.
For what little it is worth, I doubt that terrain has any more influence than the well known point that flatlands produce advanced tribes whereas other squares produce nomads. I used to think that mountain huts never produce barbs but that one got exploded. If there is anything in the terrain affects outcome notion, though, it may be I was observing some effect which reduces (but does not eliminate) the incidence of barb outcomes from such a hut.
Incidentally I have recently been noticing that the phenomenon of barbs dying off from exposure after emerging from a polar hut is not wholly isolated. Barbs which either emerge onto mountain terrain or wander there have a higher incidence of dying off than those sitting on more productive squares. When they come out in the surrounding pattern, by the way, they seem to die one per turn thereafter until two are left, then persist for a bit. Being near a city or non barb units seems to keep them interested enough to stay alive a bit longer.
If we crack the hut programming I'll be just a little sad as the game needs some truly random elements. Nevertheless more power to your testing elbows. (And Civ3 will revive us shortly, anyway.)

If you do decide to test this could you plz also take into account not only disbanding or building a city with the nomad but also removing him from the continent. I have had an incling that the number of nomads on the continent in relation to its size determines the likelyhood of recieving a nomad from a hut. So perhaps you can temporarily put a nomad in a boat b4 tipping or send him to some small island city that needs developing.

Mixam and EST,
thanks for your interest and suggestions.
I tested your "transportation" notion, Mixam. I created a map with two forested continents,
founded a capitol, eliminated the other NONE settler, and started popping huts.
In three tries I had a Nomad and put him in a boat as you suggested.
Popped 40 more huts on both continents, no more Nomads.
Continent size doesn't appear to matter in getting Nomads.
One continent was small, only 6 huts, and the other was huge, 40 or so huts.
I got a Nomad on the 3rd pop from the small continent, then got 2 more from the remaining 3 huts.
It's pretty clear, I think, that the odds of getting a Nomad from rough terrain
go from less than 1% (with an existing NONE settler) to about 25-50% without a NONE settler.
Putting him in a boat or placing him on a different continent doesn't help,
you need to use him up -- build a city or assign him to one.
While it's a long way from "cracking the hut programming", this is still a pretty useful tidbit.
An exploitable source of NONE settlers at the beginning of the game could be quite helpful.
Found two cities, then explore the rough terrain first. Pop 3 or so huts and you've got a Nomad,
found a city and repeat. Presto, instant empire.
I'm not sure yet whether the angle idea or the sequence of tipping huts
are really relevant -- still collecting data. Also, all my testing so far has been in CHEAT MODE.
Those who think this invalidates the results are free to disregard these findings.
I plan to try a game soon using Nomad hunting as a tactic. I'll let you know.
EST, I've seen hut barbs melt away next to ocean, not just polar or mountain locations.
And I agree with you that terrain seems unlikely to influence hut outcome.

Blaupanzer,
I wasn't saying that you can't get Nomads if you already have one. You can and people do. But the probably of a Nomad goes way up if you don't already have one. They are, perhaps, as common as mercenaries.
As to the connection between a NONE settler and the likelihood of a Advanced Tribe, I don't think it's the same. I've had strings of ATs in games where I kept my original NONE settler all game. But it's worth testing.

This does not specifically address nomads, but when I was researching techs coming from huts, I discovered that the probability of getting some much higher than getting others. The primary determining factor here seemed to be the list of possible techs at the time a hut was tipped, since probablities could change dramatically as the list changed. This supports samson's idea that results are based mostly on underlying probabilities than can be tested for and discovered. The randomized part of a hut result is secondary and I believe that it is somehow based on the computer's clock since so many players report pairs and/or clusters of similar results at approximately the same time.

Hmmm... apparently it didn't work, probably my test was flawed... entered a hut with a warrior, was a city, went back to a save, changed terrain to mountain and still gave me a city...
Ok... heres something... I opened 20 huts on a large map, only capital city, 10 advanced tribes, 6 units, 3 techs, 2 money, disbanded second settler, went to a new continent, three advanced tribes, then a tech, then a nomad, then tech, advanced tribe, barbs, tech. Another continent, advanced tribe, tech, unit, unit, barbs. Another continent, nomads.
Opened all huts on continent, 6 barbs, 4 nomads, 22 advanced tribes, 10 units, 575 gold total, 12 techs.

War,
I agree with you than 25% is too high for the occurance of nomads in general. In my test the next hut was always popped right after disbanding the nomad. If using up the nomad is a trigger of some kind, then perhaps waiting to found a city with one until just before popping another hut might raise the odds of getting a nomad.
Also, I was popping huts in a specific order in the hut pattern -- lower left, upper left, lower right, upper right. Sometimes every hut in a pattern was nomad. The next pattern might yield none at all.
I really don't know if there's something here or not. It's perplexing.

Shade,
There are six possible outcomes from a hut: units, barbs, techs, tribes, nomads, and gold. And there is certainly a random selection factor at work. But the probabilities of each of those of outcomes are not equal. If you think they are, you haven't been paying attention.
Furthermore, there are clearly conditions under which some of those outcomes are unavailable:
1) before you found your capitol, barbs, nomads, and tribes almost never appear.
2) after Invention techs disappear as an outcome.
3) on rough terrain, you get nomads but never tribes.
4) if you already have a NONE settler, nomads are much more rare than if you don't.
Obviously the hut-algorythm is nowhere near as simplistic as you would have it. Certain conditions are being checked in order to filter the results. If a "trigger" event occurs which alters the probability of an outcome, perhaps the predictability of the outcome immediately after that event is higher. This is the kind of thing we are investigating.
SG,
I agree about variable control. This is why I have been using CHEAT MODE in very artificial circumstances to test ideas. If any of the ideas seem valid under strictly controlled conditions then they can be tried in game play.
Latest test:
Playing as the white civ, I tried a bunch of starts until I got one with a hut that could be popped immediately in 4000BC in one move by the first settler, then saved the game. Then I loaded Civ2 onto two computers where it had never been installed. I copied the save to each machine, loaded it and popped the hut. I did 12 reload/pops on each machine, plus another dozen pops on the original machine.
The sequence of results was different on each machine. Since initial conditions were identical (even the history of civ-play on 2 of them), there seems to be a true random element involved in the selection of the outcome. However, each machine gave statistically similar results: 8 or 9 mercenaries and a couple of gold or techs.

samson,
yes, the underlying probabilities become even more evident after a 1000 or more tips of the same hut, reloading before each tip. The percentages come out neatly divided. In your 4000 bc example, I forget the actual percentages, but it was something like 1/6 techs, 1/6 gold and 2/3 units for the results. (maybe it was 1/4, 1/4,1/2, Ribannah can tell you that I'm not to good at splitting percentages!) Even sub-groups like gold and techs had their own probabilities. For example, I believe it was 25g 1/6, 100g 1/6 and 50g 2/3 of the time. For the techs coming out of that same hut (starting with no free ones) I got the following percentages after 304 tech results in about 2000 tips (This was a while ago and I'm not positive about the 2000, as I was only interested in tech results at that time):
Pottery 18%
Alphabet 16%
Warrior Code 22%
Horseback Riding 26%
Bronze Working 7%
Masonry 10%
Ceremonial Burial 1%
This certainly is NOT random! After this I tried another hut on a different kind of terrain. The probabilities were roughly the same, although this time Warrior Code beat out Horseback Riding at about the same rate as above, with just minor changes for the other techs. Once a tech is discovered, a new set of probabilities comes into effect the next time there is a tech result. To those who say I get CB from a hut a lot, I'm sure they do, when the probabilities change as the list of eligible candidates changes.
In the same way, the presence or absence of NON settlers and/or nomads has a big effect on the probability of a nomad result, as does the terrain on which the hut is found. I don't believe other things like previous results, the game year, the unit doing the tipping, position in the pattern or direction from which the tip comes from are factors in the equation, and have to agree with shade that programmers like to keep things relatively simple, because I am one myself.

Solo,
I notice the seven techs you found at 4000BC with a no-tech start are the seven first researchable techs. I wonder if the techs possible from a hut at any time are always the same as those offered for research. And if so, is it the last offering or the next offering that is available from a hut?
If this was known, there might be better times to tip huts for techs. You might know, for example, that Warrior Code was unavailble and therefore needn't worry about getting it from a hut. This should be testable.
Also, what civ was used for the 2000 tip test? I wonder if the percentages of those techs match up with the civ-specific preferences that the SGs found for starting techs.
Another thing.
Is the distribution of results from single hut reload tests the same as the distribution from multiple hut one-tip tests? The latter, of course, would be what counts in game play.

Shade,
Just because something is not perfectly predictable doesn't mean that the probabilities behind it can't be determined.
Look, we know that the program tries to compensate for poor starting locations by giving free starting techs. And that it attempts to handicap or help civs that are ahead or behind in the tech race by adjusting their research costs. Clearly there is play-balancing at work there.
Is it inconceivable to you that hut results might be used for play-balancing also? That the probabilities might be skewed towards what it thinks you need or don't need? Or in line with what a civ's style of play is?
Has anyone tested hut results using different Power rankings?
Or different levels? Are techs more plentiful at Chieftain than at Deity? There are lots of intelligent ways in which huts could have been used to vary the game. Complete randomness is only one of them.

SG2,
That's consistent with my nomad testing. Up to a 50% chance of a new nomad if the next hut is tipped on the same turn as the last nomad is used up.
"Sorry, no - been there, done that"
You mean any tech is possible at any time as long as you have the pre-requisites?
