Definition at line 36 of file benders.pxi.

bendersexit()

def bendersexit

(

self

)

calls exit method of Benders decomposition

Definition at line 16 of file benders.pxi.

bendersexitpre()

def bendersexitpre

(

self

)

informs the Benders decomposition that the presolving process has been completed

Definition at line 24 of file benders.pxi.

bendersexitsol()

def bendersexitsol

(

self

)

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

bendersfree()

def bendersfree

(

self

)

calls destructor and frees memory of Benders decomposition 

Definition at line 8 of file benders.pxi.

bendersfreesub()

def bendersfreesub	(		self,
			probnumber
	)

frees the subproblems

Definition at line 57 of file benders.pxi.
