Detailed Description
constraint handler for pseudo Boolean constraints
The constraint handler deals with pseudo Boolean constraints. These are constraints of the form
\[ \mbox{lhs} \leq \sum_{k=0}^m c_k \cdot x_k + \sum_{i=0}^n c_i \cdot \prod_{j \in I_i} x_j \leq \mbox{rhs} \]
where all x are binary and all c are integer

◆ SCIP_DECL_SORTPTRCOMP() [1/2]
|
static |
comparison method for sorting and-resultants according to their problem index, which is used instead of the original index because the implicit resultants are shuffled when creating the constraints that otherwise results in shuffled problem copies, if an and-resultant is fixed, it will be put in front with respect to its original index if an and-resultant is negated, it will be put in front of its negation counterpart

|
static |
