Dear diary, on Sun, Mar 03, 2002 at 06:10:42AM CET, I got a letter,
where Raahul Kumar <raahul_da_man@xxxxxxxxx> told me, that...

This we already have. We're increasing the desire to research certain tech
everytime when we think it would be cool to have some unit/building which
requires this tech.

Huh.. useless? Oh well..

See advdomestic.c:ai_eval_buildings().

      if (id == B_GREAT) {
        values[id] =
            (total_bulbs_required(pplayer) * (100 - game.freecost)) * t *
            (game.nplayers - 2) / (game.nplayers * 100);
      }

for your Great Library. All wonders and buildings are considered there.
Techdesires for security buildings are maybe also modified in
advmilitary.c:assess_danger().

See each fourth function in aiunit.c and advmilitary.c ;)).

> Production - Sanitation, aqueduct

advdomestic.c

> Transport - railroad.

Ok. To be honest, I've no idea how/where this is considered.

> Overwhelming science lead - philosophy, republic, railroad, the wonder Darwins
> Voyage, all the science wonders.

Ad wonders, advdomestic.c - for the rest, we rate high techs giving us many
other techs available.
