- 15 THE PROBLEM: • Silly/huge number of potential results. • Needle in a haystack most potential results wrong • Generating solutions algorithmically is hard. Furthermore, any solution should be: • Timel…
- 16 GENETIC ALGORITHMS! • Find acceptable solutions relatively quickly.
- 17 WORDOLUTION: AN EXAMPLE / DETOUR Wordolution evolves a solution from a starting population of words containing random letters
- 18 The fitness of a candidate solution is based upon its Levenshtein distance (number of different characters) from the target word.
- 19 The crossover function is synonymous with breeding new candidate solutions. The genetic information from both parents is mixed together to create two new children
