Abstract
The genetic algorithm is proving to be a useful tool in optimizing engineering design. In particular the
algorithm is well suited to structural design, A population of individual designs, randomly generated,
is changed generation-by-generation applying the principle of survival of the fittest. Engineering
design is usually very extensively constrained so the fitness of a design is assessed using an objective
function in which design constraint violations are penalized. A structured record of progress of the
algorithm is used b adapt the control parameters and also forms the basis of heuristics leading to
combinatorial space reduction for monotonic and non-monotonic data.
