Q

varying mutation step size with constant function, implications?

A

constant function

  1. changes in sigma are independent from search process
  2. strong user control
  3. sigma is fully predictable
  4. given sigma acts on every individual in population

Q

varying mutation step size with function which is updated after every nth steps by the 1/5 success rule, implications?

A
  1. changes in sigma are based on feedback from search process
  2. some user control of sigma by the 1/5 rule formula
  3. sigma is not predictable
  4. sigma acts on all indidividuals in pop

Q

varying mutation step size by assigning peronal sigma to each individual, implications?

A
  1. changes in sigma are result of natural selection
  2. almost no user control
  3. sigma is not predictable
  4. sigma acts on a single individual

Q

2 types of evidence

A
  1. absolute evidence: predefined events can trigger change

> direction and magnitude of change are fixed

  1. relative evidence: compare values through solutions created with them

> direciton and change of magnitude is not fixed
