Member Function Documentation

def benderscreatesub	(		self,
			probnumber
	)

creates the subproblems and registers it with the Benders decomposition struct 

Definition at line 35 of file benders.pxi.

def bendersexit

(

self

)

calls exit method of Benders decomposition

Definition at line 15 of file benders.pxi.

def bendersexitpre

(

self

)

informs the Benders decomposition that the presolving process has been completed

Definition at line 23 of file benders.pxi.

def bendersexitsol

(

self

)

informs Benders decomposition that the branch and bound process data is being freed

Definition at line 31 of file benders.pxi.

def bendersfree

(

self

)

calls destructor and frees memory of Benders decomposition 

Definition at line 7 of file benders.pxi.

def bendersfreesub	(		self,
			probnumber
	)

frees the subproblems

Definition at line 56 of file benders.pxi.

def bendersgetvar	(		self,
			variable,
			probnumber
	)

Returns the corresponding master or subproblem variable for the given variable. This provides a call back for the variable mapping between the master and subproblems.

(

self

)

informs Benders decomposition that the branch and bound process is being started 

Definition at line 27 of file benders.pxi.

def benderspostsolve	(		self,

Definition at line 52 of file benders.pxi.

def benderspresubsolve	(		self,
			solution,
			enfotype,
			checkint
	)

sets the pre subproblem solve callback of Benders decomposition 

Definition at line 40 of file benders.pxi.
