CP problems arise in many scientific and engineering disciplines. It not only returns local maximum and minimum but also the global ones that are important for many applications. Here, "programming" refers to the arrangement of a plan This can help to ensure that businesses make decisions that are in line with their goals and objectives. This seems reasonable, because we would expect the wetted perimeter to decrease (and hydraulic radius to increase) as the geometry of the open channel becomes more like a semicircle. (If you dont see it, that probably means you need to enable the Solver add-in.). In a special case of mathematical programming, linear programming is also known as mathematical optimization. RT=Real-Time, EOD=End of Day, PD=Previous Day. The optimization process will look at various combinations of investments and select the best one based on the constraints that have been set.
