SCIP Doxygen Documentation: Global Problem

methods to create, read and modify a global problem together with its callbacks

creates empty problem and initializes all solving data structures (the objective sense is set to MINIMIZE) If the problem type requires the use of variable pricers, these pricers should be added to the problem with calls to SCIPactivatePricer(). These pricers are automatically deactivated, when the problem is freed.

Returns: SCIP_OKAY is returned if everything worked. otherwise a suitable error code is passed. see SCIP_RETCODE for a complete list of error codes.

Precondition

This method can be called if scip is in one of the following stages:

Postcondition

After calling this method, SCIP reaches the following stage:

◆ SCIPgetOrigObjoffset() ◆ SCIPgetOrigObjscale() ◆ SCIPgetTransObjoffset() ◆ SCIPgetTransObjscale() ◆ SCIPsetObjlimit()

sets limit on objective function, such that only solutions better than this limit are accepted

Note: SCIP will only look for solutions with a strictly better objective value, thus, e.g., prune all branch-and-bound nodes with dual bound equal or worse to the objective limit. However, SCIP will also collect solutions with objective value worse than the objective limit and use them to run improvement heuristics on them.; If SCIP can prove that there exists no solution with a strictly better objective value, the solving status will normally be infeasible (the objective limit is interpreted as part of the problem). The only exception is that by chance, SCIP found a solution with the same objective value and thus proved the optimality of this solution, resulting in solution status optimal.

Returns: SCIP_OKAY is returned if everything worked. otherwise a suitable error code is passed. see SCIP_RETCODE for a complete list of error codes.

Precondition

This method can be called if scip is in one of the following stages:

◆ SCIPgetObjlimit() ◆ SCIPsetObjIntegral()

informs SCIP, that the objective value is always integral in every feasible solution

Returns: SCIP_OKAY is returned if everything worked. otherwise a suitable error code is passed. see SCIP_RETCODE for a complete list of error codes.

Precondition

This method can be called if scip is in one of the following stages:

Note: This function should be used to inform SCIP that the objective function is integral, helping to improve the performance. This is useful when using column generation. If no column generation (pricing) is used, SCIP automatically detects whether the objective function is integral or can be scaled to be integral. However, in any case, the user has to make sure that no variable is added during the solving process that destroys this property.

◆ SCIPisObjIntegral()

Precondition

This method can be called if scip is in one of the following stages:

Note: If no pricing is performed, SCIP automatically detects whether the objective function is integral or can be scaled to be integral, helping to improve performance. This function returns the result. Otherwise SCIPsetObjIntegral() can be used to inform SCIP. However, in any case, the user has to make sure that no variable is added during the solving process that destroys this property.

◆ SCIPgetVars()

gets array with active problem variables

Returns: array with active problem variables

Precondition

This method can be called if scip is in one of the following stages:

Warning: If your are using the methods which add or change bound of variables (e.g., SCIPchgVarType(), SCIPfixVar(), SCIPaggregateVars(), and SCIPmultiaggregateVar()), it can happen that the internal variable array (which is accessed via this method) gets resized and/or resorted. This can invalid the data pointer which is returned by this method.

Note: Variables in the array are ordered: binaries first, then integers, implicit integers and continuous last.

◆ SCIPdelCons()

globally removes constraint from all subproblems; removes constraint from the constraint set change data of the node, where it was added, or from the problem, if it was a problem constraint

Returns: SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See SCIP_RETCODE for a complete list of error codes.

Precondition

This method can be called if scip is in one of the following stages:
