Checkpoint 6 -- Population

slide-2
SLIDE 2

What
you
will
be
doing


  • Goals:

  • Experiment
with
different
crossover
/
mutation


rates


  • Experiment
with
a
variety
of
evolutionary
strategies


for
controlling
population


  • More
statistics
gathering.

  • Reminder:
all
checkpoints
to
contribute
to
what


eventually
will
be
reported
in
your
final
report
/
 presentation.

Selection


  • Crossover

  • Compare:

  • Crossover
rate:
0

  • Crossover
rate
=
0.25

  • Crossover
rate
=
0.50

  • Crossover
rate
=
0.75

  • Crossover
rate
=
1.0

  • Maintain
0.001
mutation
rate

Selection


  • Mutation

  • Compare:

  • Mutation
rate:
0.001

  • Mutation
rate
0.01

  • Mutation
rate
0.05

  • Maintain
75%
crossover
rate.

Population
Parameters


  • Tasks:

  • Choose
2
of
the
3
evolutionary
strategies

  • ES
(µ
+
λ)

  • Steady
State


  • Variable
Population

  • Or

  • Choose
3
population
sizes

  • Small,
medium,
and
large

  • Compare
EA
convergence

Comparisons


  • Keep

other
parameters
constant

  • Crossover

mutation
operators

  • Selection
Mechanism

  • Crossover

Mapping

  • Use
values
that
showed
most
promise
in


previous
checkpoints.

Report


  • Be
sure
to
include:

  • Which
evolutionary
strategies
you
chose
(with


descriptions)


  • Include:

  • Summary
of
runs
(best,
worst,
avg
/
generation)

  • Conclusions
on
which
seems
most
promising.
