Two innovative GA-based techniques are developed by using different strategies for the minimization of a suitably defined cost function. The first implementation is based on a set of parallel GA-based optimization sub-processes, whereas the other consists of a single process based on a variable length coding of the GA chromosomes. A set of representative test cases is analyzed for assessing potentialities and current limitations of the proposed strategy. date: 2011-01 date_type: published institution: University of Trento department: informaticat refereed: FALSE referencetext: 1.
