For the Unit commitment problem using GA, a chromosome represents the on/off status of each unit for a given load demand. Define the heuristic function used 2 8 3 1 2 3. The overall structure of the algorithm is based on two ideas: tree-based decomposition of a graph-structured LP [19] and the The other ones wouldn't even come close to solving the 15-puzzle. This process can be used to solve a wide variety of problems, including ones that have nothing to do with computers. This code is a demo of using Genetic Algorithms (GA) to solve a simple constrained multi-objective optimization (MOO) problem. After the random choice of a number selected number of iterations and the output of the algorithm is the best solution found in the last population or, in some cases, the best solution found during the evolution of the algorithm. Heuristic used in the algorithm is the City Block Distance between the Current state and the Goal State.
