Try one or both of the following for variable extra-credit.
- Research the maximum cut problem problem and find some that are
considered difficult to solve.
Try your favorite GA program on them.
- See if you can get your favorite GA program to converge on the
``hitchhiking'' problem that we discussed in class.
Consider these 8 schemas:

Define a fitness function f(x), where x is a 64-bit string,
to be 8 times the number of these schemas it contains, and 0 otherwise.
So f(x) = 64 if x is all 64 bits 1,
and f(x) = 0 if x is all 0 bits.
This extra credit assignment is due by 5pm

Oops, that's Memorial Day.
How about the next class.
There are three things to turn in electronically using the
submit command:
- A listing of your objective (fitness) function from the SGA-C,
aGA.java, simple_ga_prog.c
or simple_ga_prog.java source code,
plus any other procedures or code you change.
- A listing of your best runs of SGA-C, aGA.java,
or simple_ga_prog.
DO NOT include all generations!
Use the script command and then edit out all but the first few,
a middle few, and the last few generations.
- A write-up answering these questions
describing how you optimized the function using genetic
algorithms and what you learned (about one or two single-spaced page),
and
what problems you encountered while designing, implementing, and
debugging your program and how you solved those problems.
- Your write-up should clearly describe your encoding scheme, fitness
function, crossover operators tried, mutation operators tried,
and parameters that led to successful runs (population size, crossover
and mutation probabilities).
Use the submit command
to turn in file copies of all of the above.
Place them in the Pr8 (pea are eight) directory of MCS770.
