PPT-Introduction to Algorithms

Greedy Algorithms CSE 680 Prof Roger Crawfis Optimization Problems For most optimization problems you want to find not just a solution but the best solution A greedy algorithm . Some of the fastest known algorithms for certain tasks rely on chance. Stochastic/Randomized Algorithms. Two common variations. Monte Carlo. Las Vegas.
