Resource Probability ratios

[ZergMazter]

Could anyone help me understand this example?

Titanium:

-31 players on the map
-160 Appearance ratio
-800 Disappearance probability

For appearance ratio: 160X31\133=37%
For disappearance probability: Can anyone explain what 1 in 800 means?

Conclusion:

Appearance ratio will be 37% every turn for Titanium.
Disappearance probability is a mystery to me. I never took probability classes in high school, and google hasn't been very efficient trying to teach me.

That being said is 1 in 800 close to around 7% of disappearance probability? I'm just guessing from a number I saw online about 1 in 100 which was 63.4%, but I am clueless about the math.

Trying to mod my resources. Any help will be appreciated.

"Appearance Ratio" is for a game without pre-set resources. This poorly stated term refers to how many of that type of resource will appear at the start of the game, only. In an 8-player game, a value of "160" means 2 such resources will be in play; 160/8 = 20 which implies that the equation resulting in the actual number of said resource is ((AR/#players = N)/10).

"Disappearance" - "800" = a 1 in 800 chance of the resource "disappearing" = 0.125% per turn. (1 in 100 = 1%; 1/8th of that is 0.125)

Note that resources never actually "disappear;" they reappear elsewhere in appropriate terrain, with the total on the map never dropping below the AR.

Wow this is WAY off from what I thought it meant. I thought I could build a resource which would eventually cease to exist by exhausting it

If it's any consolation (doubtful ) that's what I thought/hoped at first, too.

I am not sure that is correct, Oz. As a test, I generated a large number of standard sized maps with the editor, with varied numbers of civilizations in the maps. Then I painstakingly counted the number of strategic resources on each map. The result that I got was that on each map, the number of strategic resources was equal to plus or minus 1 of the number of players. For a game with eight civilizations, there would be between 7 and 9 of each strategic resource on the map.

I think that the appearance number refers to the possibility of a given resource appearing on that particular tile, but I am not at all sure that is correct. What might be a possible check is assign the appearance ratio to "0"-Zero, and then have a fairly high disappear number, and see if the resource ends up being exhausted.

This is what the Civ3ConquestEdit says those questions:

Actually it can completly disappear if there is no other place for it to reappear. There is a chance however that it will reappear at the excatly same spot.

The map "Warlust" in the PTW-scenario-folder is such an example. There is only one source of oil and only one other free place of tundra, desert and whatever.

When playing the unchanged map, the only desert place was occupied by a wandering salpeter resource and than the oil source was exhausted, it completly dissappeared and never come back.

This limited the game somewhat...

It seems to me however that a resource will never exhaust if you build a city on top of it. Can someone confirm that?

@timerover51 - Interesting ...
@Civinator - Great minds think alike - That's where I "refreshed" my memory (what's left of it anyway ...) from.

Good point
