It describes the new operators and strategies included in PIKAIA 1.2, their coding implementation, and the new control variable settings that allows these new options to be used. Chapter 2 is my attempt to convince current PIKAIA users that switching to PIKAIA 1.2 is worth the (small) effort. It is a performance study of various algorithmic versions of PIKAIA, tested again a suite of maximization problems I have been developing and using over the years whenever I experimented with new strategies and operators. The third and final chapter discusses three topics that I thought could be of interest to some current or potential PIKAIA users out there, although they have nothing really to do with PIKAIA 1.2 specifically: combinatorial optimization with PIKAIA; a parallel implementation of PIKAIA; and PIKAIA in computing languages other than plain old dumb tough FORTRAN-77.
