Behaviors by Example: Patrol Sequences and Looking for Cover

This tutorial looks into the behaviors inside release #10 of the AI Sandbox, in particular the patrol sequence of the red bots and the seeking cover and hiding behaviors of the yellow bots. Both of these are implemented using a behavior tree, and you'll see how these were built and how they can be improved.

Dynamic Decisions: Building AI That Can Change Its Mind

One of the biggest challenges of building a decision-making and control system is making sure it can change its mind. It mustn't happen too often, but should also be responsive to important changes. In this masterclass, you'll learn how to build hierarchical logic that can adapt to changes — using examples as decision trees, HTN planners, and behavior trees.

A Practical Introduction to Reinforcement Learning for Games (Version ...

Back by popular demand, this introductory session about reinforcement learning will cover how reinforcement learning works in practice, what are states / actions / policies / values, why RL is so similar to planning and how it can be used to learn heuristics to speed up search. You'll also see two examples in practice, one involving decision trees and the other motion planning.
