buildGenExprObj()

def pyscipopt.expr.buildGenExprObj

(

expr

)

helper function to generate an object of type GenExpr

Definition at line 116 of file expr.pxi.

cos()

def pyscipopt.expr.cos

(

expr

)

returns expression with cos-function

Definition at line 635 of file expr.pxi.

exp()

def pyscipopt.expr.exp

(

expr

)

returns expression with exp-function

expr_to_array()

def pyscipopt.expr.expr_to_array	(		expr,
			nodes
	)

adds expression to array

Definition at line 657 of file expr.pxi.

expr_to_nodes()

def pyscipopt.expr.expr_to_nodes

(

expr

quickprod()

def pyscipopt.expr.quickprod

(

termlist

)

multiply linear expressions and constants by avoiding intermediate 
data structures and multiplying terms inplace

Definition at line 366 of file expr.pxi.

quicksum()

def pyscipopt.expr.quicksum

(

termlist

)

add linear expressions and constants much faster than Python's sum
by avoiding intermediate data structures and adding terms inplace

Definition at line 357 of file expr.pxi.

sin()

def pyscipopt.expr.sin

(

expr

)

returns expression with sin-function

Definition at line 632 of file expr.pxi.
