{
// "maxRoamingHeroes" - AI will never recruit new heroes above this value.
// Note that AI might end up with more heroes - due to prisons or if he has large number of heroes on start
//
// "maxpass" - ???
//
// "mainHeroTurnDistanceLimit" - AI will only run pathfinding for specified number of turns for his main hero.
// "scoutHeroTurnDistanceLimit" - AI will only run pathfinding for specified number of turns for his secondary (scout) heroes
// Limiting this will make AI faster, but may result in AI being unable to discover objects outside of this range
//
// "maxGoldPressure" - ???
//
// "useTroopsFromGarrisons" - AI can take troops from garrisons on map.
// Note that at the moment AI will not deliberately seek out such garrisons, he can only take troops from them when passing through.
// This option is always disabled on H3 RoE campaign maps to be in line with H3 AI
//
// "openMap" - AI will use map reveal cheat if cheats are enabled and AI is not allied with human player
// This improves AI decision making, but may lead AI to deliberately targeting targets that he should not be able to see at the moment
//
// "allowObjectGraph" - if used, AI will build "cache" for pathfinder on first turn, which should make AI faster. Requires openMap.
//
// "pathfinderBucketsCount" - ???
// "pathfinderBucketSize" - ???
//
// "retreatThresholdRelative" - AI will consider retreating from battle only if his troops are less than specified ratio compated to enemy
// "retreatThresholdAbsolute" - AI will consider retreating from battle only if total fight value of his troops are less than specified value
//
// "maxArmyLossTarget" - AI will try keep army loss below specified target
//
// "safeAttackRatio" - TODO: figure out how exactly it affects AI decision making
//
// "useFuzzy" - allow using of fuzzy logic. TODO: better description
