Subject: GA Updates 

The following plots are ittereations if the test loop that add increasing improvements to the GA.

The first plot shows the GA's behavoir unaltered from our previous runs (80% roulette, 20% tournament elite selection on).

The second plots shows when we use 90% rank selection and 10% tournament, elite selection off.

Plot 3 shows when we add an offset to restrict the values of the fitness function to be more within the range of the main loop.

Plot 4 shows when we add a gaussean mutation function that is applied to crossover individuals (rate and gaussean width chosen by guess).

 

The following are papers I have looked at while modifing the GA (not nessisaraly recently).
