Another low variance long running session

This will probably be the last parameter optimizing session, as parameter optimizing does not bring the expected results.

The average fitness never exceeds 1000. After 1000 generations there is an improvement in the maximum values, but the no further advancements.
Have a look at the robots after 0, 300, 1000 and 2216 generations.

A long running low variance breeding session

This breeding session generated the absolute maximum average (and max) fitness. Relatively fast it rises to more than 10000 in average. That means that more than half of the individuals of a population could win their matches against the reference robot.
Why could there no further improvement? No idea.
See the robots in action after:
0, 1000, 2000 and 2384 generations

Low variance initial generation

As the performace of the results of parameter optimizing did never get even near the results of the manually designed fuzzy controllers, I tryed to make the inital generation almost equal to the manually choosen parameters (low variance). The GA sould not find a better solutioion somewhere in the waste area of parameters, but find an optimized solution staring at a almost optimal solution.
Here are the results of that.

The fitness rises immediately to a much higher average and maximum than in the sessions with random initial generation (see the results in older posts).
Here are some of the best performers of their generations. The violet sumo is the 'breeded' one.

• 0 generation
• 1 generation
• 100 generations
• 500 generations
• 800 generations

Another long running breeding session

See the behaviour after several generations.

• 1 generation
• 370 generations
• 1354 generations
• 2168 generations
• 3066 generations
• 4116 generations

A long running breeding session

I let a session run for several days (on my not very fast computer) to see what happens after several thousand generations.

The result of that session shows that a minimum improvement can be achieved after a view hundred generations.
Check the behaviour of the fittest individual in that phase.

The pink sumo robot contains the 'breeded' controller whereas the blue one is controlled by a manually designed fuzzy controller. Obviously the breeded robot does not have a chance towin against the manually designed one. Even not after more than 1900 generations.
Here are some more breeded robots after the increase of fitness at about 3500 generations.
