In this blog post I model a support vector machine in Python. Previously, I modeled and solved the quadratic assignment problem (QAP) in Python using Pyomo (+). I described that the “similarity” of two facilities could be a reason for putting them closer to each other when assigning them to a set of pre-determined positions. […]
This post introduces gradient descent optimization in R, using the nloptr package. For solving transport problems or network modelling problems, linear programming will suffice. Nevertheless, depending on the topic at hand, non-linear programming might become relevant when considering additional constraints or objectives that are non-linear. R provides a package for solving non-linear problems: nloptr In […]
