-  Additional members are generated using crossover.
-  Crossover takes two parent hypothesis from the current
population and creates two offspring hypothesis by recombining
portions of both parents.  The parents are chosen probabilistically
using the same formula mentioned above.  Now the new generation
contains the desired number of members.
-  Now a certain fraction   of these members are chosen at
random, and random mutations are performed. of these members are chosen at
random, and random mutations are performed.
-  randomized, parallel beam search for hypothesis that perform
well according to the fitness function.
