Theory

1. Explain: DE’s build new examples by extrapolating between known ones.
   • how does this method maintain associations between variables?
2. Explain the following DE constants:
   • What is np and how is it used?
   • What is cf and how is it used?
   • What is f and how is it used?
3. For each of np,cf,f what would happen in those values were doubled or halved?
4. Give a reasonable size for the frontier with respect to the number of decisions

Practice

1. Write down, in 10 lines or less, pseudo-code for extrapolation in DE.
