Linear integer program in R with lpSolve

In the previous post (https://www.supplychaindataanalytics.com/solving-a-simple-linear-programming-problem-using-lpsolve-in-r/) I demonstrated how a simple linear optimization problem can be modelled and solved using the lpSolve package in R. In this post I want to add the topic of modelling integer variables. In the previous post we maximized objective function 2x + 3y, with the constraint that x + y […]
