While these topics are examined within the framework of time-varying networks, each chapter is self-contained so that each can be read — and used — separately.

However, they have not produced a significant breakthrough in the area of nonlinear programming due to the fact that they have not addressed the issue of constraints in a systematic way. In this chapter we 1 present some issues which should be addressed while solving the general nonlinear programming problem, 2 survey several approaches which have emerged in the evolutionary computation community, and 3 discuss briefly a methodology, which may serve as a handy reference for future methods.
Introduction Every real-world problem poses constraints. Dhar and Ranganathan wrote: Virtually all decision making situations involve constraints. Depending on how the problem is visualized, they can arise as rules, data dependencies, algebraic expressions, or other forms. Superior individuals are usually given higher probabilities for survival and reproduction.
This can be a significant challenge when facing the possibility of having infeasible solutions. It might be useful, however, to operate on infeasible solutions while searching for better feasible solutions. It can mean the difference between success or failure. Sometimes constraints are helpful and can guide you in the right direction.
Later we illustrate many of these issues in the domain of nonlinear programming problems NLPs. In general, a search space S consists of two disjoint subsets of feasible and infeasible subspaces, and ZY, respectively see figure 3. During the search process we have to deal with various feasible and infeasible individuals. For example see figure 3.
A search space and its feasible and infeasible parts with a population of 15 individuals, a - o Having to operate on both feasible and infeasible solutions can affect how we design various aspects of an evolutionary algorithm. Suppose we were using some form of elitist selection.

Questions sometimes arise in designing variation operators as well. Some operators might only be applicable to feasible individuals. But without a doubt, the major concern is the design of a suitable evaluation function to treat both feasible and infeasible solutions.
