I quote below a personal portable implementation (in C++) of a classic Differential Evolution algorithm used to maximize the function f(x) = sin(x) in the domain 0 <= x <= 2pi. You can compile the program with the g++ compiler.

The Differential Evolution algorithm implements the following features:

  1. Monoparametric optimization problem (with continuous parameter)
  2. Natural representation of genotypes
  3. Genotypes of only one chromosome
  4. Number of iterations as the termination criterion
  5. Steady-State reproduction (replacement of parents and children)
  6. Crossover through breeding: v = x0 + a (x1 – x2)
  7. Climbing through breeding: v = x0 + a (x1 – x2)
