Tech costs

[del62]

Is there any info on how many beakers each tech costs on different levels, map sizes and in the light of how many known AI have that tech anywhere on this site.

Hmm. I believe the "base cost" for each can be found in the Editor. There is a formula floating around here:

Research Cost = [MM * [10*COST * (1 - N/[CL*1.75])]/(CF * 10)] - Research done so far.

I don't know what all the variables mean, though.

If you use CivAssist II, it can tell you the cost of researching any given tech, at any given time. (Assuming you are *able* to research it, at least.)

Here is the explanation of the formula:

Is there a base cost table anywhere, for people who don't have CAII or the editor (i.e. Mac users)?

The formula is in the thread mentioned and the base cost is found in the editor. There is also a stand alone calc tool in the utilities section that you can use. It will give the cost in beakers for any level and other pertinent factors.

 

[anaxagoras]

Regrettably, none of the options you mentioned work on Mac. Which is why I was wondering if there was a simple table of base values somewhere.

Well you could write a simple Excel app to do it. I did one years ago, before I found these tools. If you just want the raw beakers use the base cost for the tech for a given map size from the editor.

Here I will save you the trouble:

MM = map modifier(tech rate on world sizes tab in the editor)
Tiny 160
Small 200
Standard 240
Large 320
Huge 400

CF = AI cost factor(as on the difficulty tab in the editor)
For the purposes of the research cost formula, CF has a maximum value of 10.

Chieftain 20
Warlord 12
Regent 10
Monarch 9
Emperor 8
Demi God 7
Deity 6
Sid 4

So for each tech the cost is constant base as shown in the editor. Take Masonry it cost 4. So 4 x 240 is what I call the raw count or 960. The factor for the level is 10 for Regent, so 960 / 10 = 96. 240 is for std map.

Do it on Sid and the factor for the level is 4. Same 960 now divide by 4 and get 240 beakers.

This does not account for some of the things like user that you know that know the tech or how many civs left in the game. I have a complex Excel for that, but this is good enough.

You just need to have the base for each tech and that is in the editor. Make entries in the spread sheet each time you use it and soon you will have them all.

Maybe I am missing something. The editor does not function on Mac. This is why I asked for a table of BASE values. The math I can do, IF I have a place to start. Is it possible for a PC person to export those values to a spreadsheet?

That's what I was looking for. Thanks, Chamnix.

 

[del62]

thanks chamnix, thats what i wanted as well, with the formulae should really help

I know this thread is over a year old, but I have noticed techs on cheiftain to regent seem the same cost, at least on conquests, is this correct.

Yes, this seems correct. See Padma's post for the formula and consider what the variables stand for:

MM = map modifier(tech rate on world sizes tab in the editor)
Tiny 160
Small 200
Standard 240
Large 320
Huge 400

CF = AI cost factor(as on the difficulty tab in the editor)
For the purposes of the research cost formula, CF has a maximum value of 10.
Chieftain 10
Warlord 10
Regent 10
Monarch 9
Emperor 8
Deity 6

COST = technology cost as on the civilization advances tab in the editor.

N = number of civs on the diplomacy screen that have discovered the tech.

CL = number of civs left in the game

Two games, one on chieftain and the other one on regent should have the same tech costs given that but all else equal.
