Function Z3_optimize_assert_soft 

pub unsafe extern "C" fn Z3_optimize_assert_soft(
    c: Z3_context,
    o: Z3_optimize,
    a: Z3_ast,
    weight: Z3_string,
    id: Option<Z3_symbol>,
) -> c_uint

Assert soft constraint to the optimization context.

• c: context
• o: optimization context
• a: formula
• weight: a penalty for violating soft constraint. Negative weights convert into rewards.
• id: optional identifier to group soft constraints
