The easiest way to print "Hello, World!"? Genetic programming, of course!

1. Write a brainfuck (wikipedia or esolang) interpreter (see VM.java).

2. Use a hillclimber or a genetic algorithm to create a brainfuck program that prints "Hello, World!".

3. Use the interpreter from (1) to execute the program from (2).

Done.

Supplied are, respectively, HillClimberMain and GeneticMain. Note that both supply suboptimal solutions at best and might fail at coming up with ANY solution at all (especially the GeneticMain)

• at least before your patience runs out.

Generally, the HillClimber quickly finds a bad solution (local minimum) while the Genetic Algorithm finds a better one but takes a lot longer.

That said, program terminates when it finds a program that prints exactly "Hello, World!". Theoretically it could find shorter valid programs if we'd leave it running longer.

Note that the instruction limit during testing will mean that only programs that terminate in less than n steps are considered.
