Reflector shape design using merit function and genetic algorithm

The article presents results of research on the calculation of the shape of a mirror reflector that has not a rotating symmetry. The objective function ensures the highest possible average value of illuminance and uniformity ratio of illuminance. Optimization calculations were carried out for different light source dimensions with the use of merit function. In this paper two strategies that help to get global optimum are compared. First of them is starting ten times from ten different points and find the best solution. The second is using strategy of alteration of population diversity that is executed in one, programmed process.
