moealib is a C++ library for multi-objective evolutionary algorithms.currently included moeas are:	Niched Pareto Genetic Algorithm	Nondominated Sorting Genetic Algorithm	Pareto Tree Searching Genetic Algorithm	Strength Pareto Evolutionary Algorithm	Vector Evaluated Genetic AlgorithmThis library is mainly research-oriented rather than application oriented.It is designed together with my research work on MOEA, and actually one result of my work is a new algorithm, Pareto Tree Searching Genetic Algorithm,which is also included in the library.No separate and detailed documents are available now (maybe I will do it later.),though there are comments in each head or source file.Parameters to the moea can be set either by member functions or command line arguments.'a.out --help' will give a detailed explanation for the way to enter command line arguments.See examples in knapsack/ about how a meoa program should be written.makefiles for moealib and for example programs in knapsack/ are also provided.assert() is used frequently in all my source codes, and it aims both at debuggingand at commenting. Accordingly, there are two versions both for moealib and for example programs, one optimized version(disabling assert()), the other debugging version.Please see each makefile for details.I did all the work under linux, using emacs and g++ complier(thanks to the authors).Below is a list of all the head files in moealib.AlleleStr.h        allele string class. Assign.h           class for fitness assign. Beware not all meoas use an explicit assign class.
