Phase I
•Analysis of Black Plague
Phase II
• Improving Black Plague
• Decided to experiment with thresholds and
ratios.
• Reduced reproduction threshold. Changed
ratio for environment heuristics.
Phase III: Starting Over
• Nascent strategy:
• Black Plague is conservative initially
• Decided to probabilistically make our
organism aggressive when it’s born
• Gives good trade off between risk taking
and risk averse behavior
Phase III: Starting Over
• Moving:
• Move onto food
• Move probabilistically if no food around
(conservative strategies)
• Move based on how good you expect the
environment to be
• Move away from “friends” if possible
• Move without backtracking, if possible
Phase III: Starting Over
•

Reproduction:
Do not reproduce till you have eaten
Reproduce onto food whenever possible
Force reproduction when we are sitting on a
“cache” of food which we are too full to eat.
Conclusions:
Tournament results:
• Single Player:
We finished in the top 50%, in terms of
population, in 75% of the tournament
• Multiplayer:
Our player survived in 75% of the tournament
configurations and was in top 30%, in terms of
population, in 50% of the rounds and was in the
top 50%, in terms of population, in the remaining
25%.
