In this work we consider the application of metaheuristic algorithms to the problem of fitting rectangular signals to time-data series. The application background is to search for transit signals of exoplanets in stellar photometric observation data. The presented algorithms include an Evolution Strategy and Differential Evolution; both algorithms use an efficient reduction of the search space by exactly solving a subproblem. The presented results affirm the presented methods to be promising and effective tools for the discovery of the first multi-transit planetary system.
