Systems and methods for ranking or optimizing market configurations are disclosed. Optimized configurations of stores and formats in a market bounded within a geographic area are produced. The geographic area is divided into cells, and the cell attributes are used to determine which store formats can be present. Market configurations for each cell are provided to forecasters for determining of a first fitness criteria. Market configurations are filtered based on the first fitness criteria. Impacts between market configurations are calculated. A genetic algorithm produces a plurality of market solutions. In embodiments, optimization tasks are performed in parallel.
