FindDec uses modified genetic algorithm technology to quickly solve complex optimization problems in finance, distribution, scheduling, resource allocation, manufacturing, budgeting, engineering, and more. FindDec can find optimal solutions to problems which are "unsolvable" for standard linear and non-linear optimizers. FindDec can find optimal solutions to virtually any type of problem, from the simple to the most complex; it finds not only global optimums, and also local optimums. FindDec is useful and efficient when 1. the method of an accurate decision does not know 2. the method of an accurate decision knows, but it is very difficult to implement 3. the exact optimum is not required, and the decision may be any value, which is more a set value 4. the search space is large, complex or poorly understood 5. traditional search methods fail Work consists of six steps in the application «FindDec» 1. Input of the problem 2. Option of parameters of GA 3. Option of termination conditions of GA 4. Option of output and saving 5. Searching of decisions 6. Saving of a result Steps 1, 5, 6 are compulsory. The number of variables must be no more than 70.
