) -> bool
Add a weight rule to the program.
@attention All weights and the lower bound must be positive. @param[in] backend the target backend @param[in] choice determines if the head is a choice or a disjunction @param[in] head the head atoms @param[in] head_size the number of atoms in the head @param[in] lower_bound the lower bound of the weight rule @param[in] body the weighted body literals @param[in] body_size the number of weighted literals in the body @return whether the call was successful; might set one of the following error codes:
- ::clingo_error_bad_alloc
