Weighted and Lexicographic Goal Programming Interface R package goalp version 0.3.1 Solves goal programming problems of the weighted and lexicographic type, as well as combinations of the two, as described by Ignizio (1983) <doi:10.1016/0305-0548(83)90003-5>. Allows for a simple human-readable input describing the problem as a series of equations. Relies on the 'lpSolve' package to solve the underlying linear optimisation problem.
