CS 5970 Homework 3 — Evolutionary Computation for Problem Solving

Due Wednesday, March 6, 2013

NOTE: The hardcopies of the parts of this assignment are due at the beginning of the class period. This means that if you are even a minute late, you lose 20%. If you are worried about potentially being late, turn in your assignments ahead of time. Do this by submitting them to me during office hours or by sliding them under my office door. Electronic copies are due by 4:00 pm on the due date. Submit them through D2L before the time they are due. Do not send assignments to me through email or leave them in my departmental mail box.

1. Motivation

To use evolutionary computation to solve problems, we need to apply them to particular problems. To do that, we need to (following De Jong, Evolutionary Computation: A Unified Approach, p 72):

2. Goals

The goals of this assignment are:

3. Assignment

Read the paper "Phenotype Feedback Genetic Algorithm Operators for Heuristic Encoding of Snakes within Hypercubes" by Carlson and Hougen (from the Genetic and Evolutionary Computation Conference, July 2010) then answer the questions below regarding the GA in this paper.

  1. What does an individual in the population represent?
  2. Is this a fixed-length linear object, a fixed-length nonlinear object, a variable-length linear object, or a nonlinear variable-length object?
  3. How is each individual encoded?
  4. Is this encoding genotypical or phenotypical?
  5. How is fitness calculated for each individual in the population?
  6. What reproductive operators are used?
  7. What parameters are used for each of the reproductive operators?
  8. What is the parent population size?
  9. What is the offspring population size?
  10. Is an overlapping or non-overlapping generation model used?
  11. What stopping criteria are used?
  12. What answers are returned?

4. What to Turn In

You will turn in both a typed hard copy and a machine readable electronic copy of your homework that answers the questions above.
