abstract = "This paper presents a comparison of Genetic
Programming(GP) with Simulated Annealing (SA) and
Stochastic Iterated Hill Climbing (SIHC) based on a
suite of program discovery problems which have been
previously tackled only with GP. All three search
algorithms employ the hierarchical variable length
representation for programs brought into recent
prominence with the GP paradigm. We feel it is not
intuitively obvious that mutation-based adaptive search
can handle program discovery yet, to date, for each GP
problem we have tried, SA or SIHC also work.",
