Overview

LpSolver - A Ruby gem for solving Linear Programming (LP), Quadratic Programming (QP), and Mixed Integer Programming (MIP) problems.

This gem provides a Ruby DSL for building optimization models and interfaces with the HiGHS solver via its command-line interface.

Quick Start

require 'lpsolver'

model = LpSolver::Model.new
x = model.add_variable(:x, lb: 0)
y = model.add_variable(:y, lb: 0)

model.add_constraint(:budget, (x * 2 + y) <= 100)
model.minimize
model.set_objective(x * 3 + y * 5)

solution = model.solve
puts solution.objective_value  # => 12.0
