SimplexLP
This app simplifies linear optimization problems with an objective function and constraints. It offers a graphical representation for problems with two variables, making it an ideal learning tool for students and teachers of the Simplex algorithm.
- Solves maximization and minimization problems
- Handles unlimited variables and constraints
- Supports ≤, ≥, and = inequalities
- Provides graphical representation for 2-variable problems
- Outputs calculations in fractions or decimals
- Offers accurate calculations with fractions

SimplexLP solves linear optimization problems, which can be mathematically described with an objective function and a set of constraints. With the new graphical representation (possible with 2 variables only) it is a lot easier to understand the theoretical concept of linear optimization! SimplexLP is the perfect learning companion for teachers (to set up problems) and students (to learn the Simplex algorithm). It is very easy to change coefficients and see how the solution varies. For the calculation the famous Simplex algorithm is used. With SimplexLP you can: – easily set up the objective function and the constraints; – solve maximization and minimization problems; – solve problems with unlimited number of variables and constraints; – solve problems with ≤, ≥ and = (in)equalities; – get all the possible solutions ("edges") to a problem; – get accurate calculations with fractions; – get your output in fractions or decimal values; – set a fixed value in the objective function, e.g. for fixed costs; – set the tab width (via a simple swipe gesture) to format the tableaus; – get a graphical representation of optimization problems with 2 variables. With SimplexLP linear optimization really makes fun!
