Mathematical optimization or mathematical programming is the selection of a best element, with regard to some criterion, from some set of available alternatives.Wikipedia
The latest sunset I photographed was from a hill in the north of our city. All shades of red and orange were present, as well as several well-positioned primroses. Thus, everything is set for the optimization. Converging towards the optimal photo went fast in the beginning, but slowed down after the initial photos – a typical observation for a gradient ascent procedure. I picked out the primrose with the best shape and different possible backgrounds. While I have not reached the optimum, I still like most of these pictures. Which one do you like the most?
