cornerPoints: Calculate the corner points for the polytope Ax<=b.

In relund/gMOIP: Tools for 2D and 3D Plots of Single and Multi-Objective Linear/Integer Programming Models

Calculate the corner points for the polytope Ax<=b.

Description

Calculate the corner points for the polytope Ax<=b.

Usage

cornerPoints(A, b, type = rep("c", ncol(A)), nonneg = rep(TRUE, ncol(A)))

Arguments

A	Constraint matrix.
b	Right hand side.
type	A character vector of same length as number of variables. If entry k is 'i' variable k must be integer and if 'c' continuous.
nonneg	A boolean vector of same length as number of variables. If entry k is TRUE then variable k must be non-negative.

Value

A data frame with a corner point in each row.

Examples

A <- matrix( c(3,-2, 1, 2, 4,-2,-3, 2, 1), nc = 3, byrow = TRUE)
b <- c(10, 12, 3)
cornerPoints(A, b, type = c("c", "c", "c"))
cornerPoints(A, b, type = c("i", "i", "i"))
cornerPoints(A, b, type = c("i", "c", "c"))
