ALA-EA was derived by Soak [6,7] and it showed very
good performance at the fixed charge transportation problem
and the quadratic minimum spanning-tree problem.
In general, at ALA-EA, all possible edges in network
problems correspond to each gene’s locus and all gene
values are initially set to ‘0’ (see Fig. 1). The gene values
indicate a measure to distinguish between good edges or
bad edges for the problem considered during the entire
evolutionary process. And, it first sorts all genes according
