The book, which are generalizations of the "Traveling Salesman problems" and "Assignment Problems." For each of the problems an algorithm based on 'Lexisearch Search Approach is developed to get an optimal feasible solution using 'Pattern Recognition Approach'.Each problem is studied and the necessary computational results are presented in it, and the actual computer program of the algorithm written in 'C' language is given. In the usual 'Lexi-search Algorithm for the problems developed so far, when a partial word is considered, it is first checked for feasibility. In this context the...
