LifeAI is an open source C++ library for Artificial Intelligence decision-making. It can be integrated in video games, robotics, or anything that requires simulated intelligence.

Entities and actions are created in C++ and text files with LifeAI's syntax. Entities have characteristics that describe them called "stats". They consider their value of the stats and how much they are modified to assess the "pros" and "cons" of an action. They also consider their value of other entities involved in the action and how it affects them. They can then determine an overall value for performing the action.

As stats in the simulation change, LifeAI updates the best action options for the entities. The actions can then be implemented as needed in a simulation.
