Evolves a multiplier, {"}72% more often than control sample{"} {"}PL- not fully Turing Equivalent{"}, addition of :SET and :BLOCK lead to JB language (nb a list of statements language). JB has problems with crossover -> TB which is as JB but instead of calls to other statements, these other statements are expanded in the first yielding a tree shaped syntax. Crossover operator changed to deal with sub trees! Both languages contain small numbers of global integers. TB Mutation restricted to frindges of tree, ie leaves or first level functions. Inversion: crossover within same program! Goldberg(1989, p 303) says {"}Cramer does not present any results from the use of JB in any genetic trials; however he abandoned these first efforts because of some limited computational experiments{"}.
Fitness based, to some extent, upon internals of program. Limits on prog size via fitness. Forced timeout Goldberg(1987) says timed out progs fitness was calculated.
