graph_implementation(object, arg_objs, size,
data = NA_real_)
A list of arguments to the atom.
An index into the atom.
A list of linear expressions for each argument.
A vector with two elements representing the size of the resulting expression.
A list of additional data required by the atom.
to_numeric
: Negate the value.
size_from_args
: The size of the expression.
sign_from_args
: The sign of the expression.
is_incr
: The expression is not weakly increasing in any argument.
is_decr
: The expression is weakly decreasing in every argument.
graph_implementation
: The graph implementation of the expression.
