Method "fctp"

Description

Checks inequalities for facet inducing property.

Usage

## S4 method for signature 'ieqFile': 
fctp(object,poiObject)

Arguments

object Object of class ieqFile
poiObject Object of class poiFile

Details

fctp performs a check whether the inequalities given in object are facet inducing for the polyhedron given by poiObject.

For all inequalities fctp does the following:

In a first step fctp checks if the inequality is valid. If this is not the case fctp returns the points and rays which are not valid.

In a second step fctp computes those valid points and rays which satisfy the inequality with equality and - if there are any - returns them.

Value

Returns one or more objects of class poiFile.
