A very well-bred signal compression method:

Pursuing a second improvement objective, the student group proposed to optimize both reverse and forward wavelet transform coefficients using the modified GA method. Once again, the modified GA performed better and faster than standard wavelets, locating a solution (in just 10 generations with a population of 50) superior to that of the original GA (which required 500 generations with a population of 200). These results conclusively prove the usefulness of evolving both reverse and forward wavelet transform coefficients.
