1 Genetic Algorithms and TSP
Thomas Jefferson Computer Research Project by Karl Leswing

2 Genetic Algorithms Effective in Optimization Problems
Classified as a global search heuristic Inspired by Evolutionary Biology Inheritance Mutation Selection Crossover

3 Traveling Salesman Given a number of cities and the costs of traveling from any city to any other city, what is the cheapest round-trip rout that visits each city exactly once and then returns to the starting city.

4 Traveling Salesman Continued
Dynamic Programming down to O((n^2)*2^n)‏ Find Near Optimal Solutions

5 Current Work

6 Current Work Continued
Double Point Crossover Roulette Selection Unique Fitness Algorithm Single Point Mutation Mutation Rate Variable Effectiveness Solve 50 City TSP in less than one minute

7 Ant Colony Optimization
Pheromone Trail Evaporation Rate Effective for dynamically changing graphs Useful for network routing and urban transportation systems

8 3 Dimensions Attempted Open GL with Pipe Attempted Jogl Given Up
Java Bindings for OpenGl Given Up Work on Comparison of global search hueristics

9 Extensions Finish my ant colony optimization (ACO)‏
Brute Force Automated Test Particle Swarm Optimization (PSO)‏ Neural Networking
