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.
