Python builtin overwrites (cpmpy.expressions.python_builtins)

Overwrites a number of python built-ins, so that they work over variables as expected.

List of functions

nosignatures:

all any max min sum abs

cpmpy.expressions.python_builtins.abs(element)

Overwrites the python built-in abs function, to support decision variables.

if the element given is not a CPMpy expression, the built-in is called else an Absolute functional global constraint is constructed.

cpmpy.expressions.python_builtins.all(iterable)

Overwrites python built-in all function, to support decision variables.

if iterable contains any Expression, then returns an Operator(“and”, iterable) otherwise returns whether all of the arguments are true

cpmpy.expressions.python_builtins.any(iterable)

Overwrites python built-in any function, to support decision variables.

if iterable contains an Expression, then returns an Operator(“or”, iterable) otherwise returns whether any of the arguments is true

cpmpy.expressions.python_builtins.max(*iterable, **kwargs)

Overwrites the python built-in max function, to support decision variables.

if iterable does not contain CPMpy expressions, the built-in is called else a Maximum functional global constraint is constructed; no keyword arguments are supported in that case

cpmpy.expressions.python_builtins.min(*iterable, **kwargs)

Overwrites the python built-in min function, to support decision variables.

if iterable does not contain CPMpy expressions, the built-in is called else a Minimum functional global constraint is constructed; no keyword arguments are supported in that case

cpmpy.expressions.python_builtins.sum(iterable, **kwargs)

Overwrites the python built-in sum function, to support decision variables.

if iterable does not contain CPMpy expressions, the built-in is called checks if all constants and uses built-in sum() in that case
