WebbIn simple terms, the solver starts with a random “population” of sets of input values. These sets of input values are plugged into the model and the results are evaluated relative to the target value. The sets of input values that result in a solution that’s closest to the target value are selected to create a second population of “offspring”. WebbThe simplex method is an algorithmic approach and is the principal method used today in solving complex linear programming problems. Computer programs are written to …
