Abstract
A Genetic Algorithm with real-coded chromosomes is used to solve a potential
flow problem in a contraction channel. A new uniform, successive-refinement
strategy is presented wherein the algorithm starts with a coarse solution and works
its way through multi-levels of refinements to arbitrary solution resolution. At each
level of refinement, a line-by-line sweep-through method is used to obtain incremental
solutions for various parts of the flow domain, thus reducing the number of
GA constraints. A finite difference grid was used as the objective function to evaluate
the fitness of the chromosomes. Results are very promising for five levels of
refinements totalling more than 12,000 nodes. Small population sizes were found
to be most effective, often yielding solutions in l
