chapter 8 Flashcards
1
Q
varying mutation step size with constant function, implications?
A
constant function
- changes in sigma are independent from search process
- strong user control
- sigma is fully predictable
- given sigma acts on every individual in population
2
Q
varying mutation step size with function which is updated after every nth steps by the 1/5 success rule, implications?
A
- changes in sigma are based on feedback from search process
- some user control of sigma by the 1/5 rule formula
- sigma is not predictable
- sigma acts on all indidividuals in pop
3
Q
varying mutation step size by assigning peronal sigma to each individual, implications?
A
- changes in sigma are result of natural selection
- almost no user control
- sigma is not predictable
- sigma acts on a single individual
4
Q
2 types of evidence
A
- absolute evidence: predefined events can trigger change
> direction and magnitude of change are fixed
- relative evidence: compare values through solutions created with them
> direciton and change of magnitude is not fixed
