Functions

extract(→ List[jijzepttools.modeling.utils.type.Expr])	extract element that matches the pattern
get_add_terms(...)	get terms from expression

Module Contents

extract(expr: jijzepttools.modeling.utils.type.Expr, pattern: Callable[[jijzepttools.modeling.utils.type.Expr], bool]) → List[jijzepttools.modeling.utils.type.Expr]

extract element that matches the pattern

Parameters:

• expr (Expr) – expression

• pattern (tp.Callable[[Expr], bool]) – condition

Returns:

extracted elements

Return type:

tp.List[Expr]

get_add_terms(expr: jijzepttools.modeling.utils.type.Expr) → List[jijzepttools.modeling.utils.type.Expr]

get terms from expression For example, if the input is a+b+c, this function returns [a, b, c]. Unlike jm.AddOp.terms, this function returns decomposed terms. For example, if the input is (a+b)+(c+d), this function returns [a, b, c, d] whereas jm.AddOp.terms returns [(a+b), (c+d)].

Parameters:

expr (Expr) – expression

Returns:

terms

Return type:

tp.List[Expr]

get_mul_terms(expr: jijzepttools.modeling.utils.type.Expr) → List[jijzepttools.modeling.utils.type.Expr]

get terms from expression For example, if the input is a*b*c, this function returns [a, b, c]. Unlike jm.MulOp.terms, this function returns decomposed terms. For example, if the input is (a*b)*(c*d), this function returns [a, b, c, d] whereas jm.MulOp.terms returns [(a*b), (c*d)].

Parameters:

expr (Expr) – expression

Returns:

terms

Return type:

tp.List[Expr]

get_var(var_dict: Dict[Any, jijmodeling.Subscript | jijmodeling.Placeholder | jijzepttools.modeling.utils.type.DecisionVar], var_name: str, *indices: Any) → jijzepttools.modeling.utils.type.Expr

get variable from variable dictionary This function returns a variable from variable dictionary. If the variable is not in the dictionary, this function returns jm.NumberLit(0).

Parameters:

• var_dict (tp.Dict[tp.Any, Expr]) – variable dictionary

• var_name (str) – variable name

• *indices (tp.Any) – indices of the variable

Returns:

variable

Return type:

Expr

extract_element_without_belong_to(expr: jijzepttools.modeling.utils.type.Expr) → List[jijmodeling.Element]

extract elements without This function extracts elements without belong_to from expression.

Parameters:

expr (Expr) – expression

Returns:

elements without belong_to

Return type:

tp.List[jm.Element]
