Details:
From http://freeciv.wikia.com/wiki/Forum:Some_tiny_issues (4):
(common\tech.c player_tech_upkeep)
current: (base_tech_cost) * (f * (2 * t + f + 1) + 2 * t) / 2
I think: (base_tech_cost) * (f * (2 * t - f - 1)) / 2
f is number of discovered Future Tech, t is number of discovered tech (include
"None" and Future Tech).
Also, total_research_factor is
current: EFT_TECH_COST_FACTOR + (2.5 for novice AI, 1 for other)
I think: EFT_TECH_COST_FACTOR * (2.5 for novice AI, 1 for other) and later
tech_upkeep /= members is not needed.
memo:
Future Tech cost is number of discovered tech * (base_tech_cost) *
EFT_TECH_COST_FACTOR
e.g. in civ2civ3, Future Tech 1 costs 20 * 88(87 techs + "None") *
3(effects.ruleset Tech_Cost_Factor) = 5280 bulbs needed.
Future Tech 2 costs 20 * 89(87 techs + "None" + 1 future tech) *
3(effects.ruleset Tech_Cost_Factor) = 5340 bulbs needed.
