Technology Cost
This cost of a given technology is determined by the following.
TECHS: Techs you've discovered already (including trading/pods/artifacts, but not the ones you started with) + unknown variable A - unknown variable B. MOSTTECHS: This number is equals to the max number of technologies discoved by any faction. Unknown varaible A is added to this number. DIFF: This is 1 on citizen difficulty, 2 on specialist, 3 on talent or librarian, 4 on thinker, 5 on transcend. TURNS: Number of turns.
1. Find (DIFF*4)+8. AIs instead use 29-(DIFF*3). If this number is smaller than -12 then use -12 for this number. If this number is bigger than 12, then use 12 for this number.
2. Take TECHS, and subtract TURNS/8 (or TURNS/12 with tech stagnation), to a minimum of 0 and a maximum equal to the result of step 1 (or 1.5 times the result of step 1 with tech stagnation).
3. Add the result of step 2 to the result of step 1.
4. Take (MOSTTECHS - TECHS)/5 , rounding up. Subtract this from the result of step 3, but no more than 30% the result of step 3 (rounding normally) plus 1. AIs instead divide by a number dependent on difficulty, ranging from 3 on Transcend to 8 on Citizen, and the maximum percentage ranges from 0% plus 1 on citizen to 50% plus 1 on transcend.
5. Take TECHS, and add 1 for factions with a natural penalty to research, or subtract 1 for factions with a natural bonus to research. Apply a minimum of 1. Multiply this by the result of step 4.
6. Modify by WORLDSIZE and faction and alpha(x).txt tech cost modifiers, and add 50% with tech stagnation.
