CMPUT 299 - Fall 2005 Artificial Intelligence Algorithm ! A detailed set of actions to perform or accomplish some task ! Evaluate game algorithms according to: 1. Does it meet our time constraints? 2. Does it meet our memory constraints? 3. Does it solve the task at hand? 4. Does it do so in an acceptable/realistic manner? CMPUT 299 - Fall 2005 Artificial Intelligence Describing Algorithms ! Three components to describing an algorithm ! Actions ! States !

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

Kiran Temple University Fox School of Business ‘17, Course Hero Intern

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

Dana University of Pennsylvania ‘17, Course Hero Intern

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
