fctp-method {rPorta} | R Documentation |
Checks inequalities for facet inducing property.
## S4 method for signature 'ieqFile': fctp(object,poiObject)
object |
Object of class ieqFile |
poiObject |
Object of class poiFile |
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.
Returns one or more objects of class poiFile
.
