Linear programming in r
Nettet6. jul. 2024 · We can however come up with an alternative problem where there is a more clear discrepancy between the minimization of the regression problem (minimizing the sum of squares of the residuals) and plugging that solution into the linear programming, or minimizing more holistically the outcome of the linear programming. Nettet14. jul. 2012 · Linear programming is a valuable instrument when it comes to decision making. This post shows how R in conjunction with the lpSolveAPI package, can be used to build a linear programming model and to analyse its results. The lpSolveAPI package provides a complete implementation of the lp_solve API. The example case; A trading …
