◆ SCIPvarIsRelaxationOnly()
returns whether a variable has been introduced to define a relaxation
These variables are only valid for the current SCIP solve round, they are not contained in any (checked) constraints, but may be used in cutting planes, for example. Relaxation-only variables are not copied by SCIPcopyVars and cuts that contain these variables are not added as linear constraints when restarting or transferring information from a copied SCIP to a SCIP. Also conflicts with relaxation-only variables are not generated at the moment. Relaxation-only variables do not appear in the objective.

Relaxation-only variables are not copied by SCIPcopyVars and cuts that contain these variables are not added as linear constraints when restarting or transferring information from a copied SCIP to a SCIP. Also conflicts with relaxation-only variables are not generated at the moment.

Transforms a given linear sum of variables, that is a_1*x_1 + ... + a_n*x_n + c into a corresponding linear sum of active variables, that is b_1*y_1 + ... + b_m*y_m + d.
If the number of needed active variables is greater than the available slots in the variable array, nothing happens except that the required size is stored in the corresponding variable (requiredsize). Otherwise, the active variable representation is stored in the variable array, scalar array and constant.
The reason for this approach is that we cannot reallocate memory, since we do not know how the memory has been allocated (e.g., by a C++ 'new' or SCIP functions).
- 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
scipis in one of the following stages:
- Note
- The resulting linear sum is stored into the given variable array, scalar array, and constant. That means the given entries are overwritten.
- That method can be used to convert a single variables into variable space of active variables. Therefore call the method with the linear sum 1.0*x + 0.0.
- Parameters
-
scip SCIP data structure vars variable array x_1, ..., x_n in the linear sum which will be overwritten by the variable array y_1, ..., y_m in the linear sum w.r.t. active variables scalars scalars a_1, ..., a_n in linear sum which will be overwritten to the scalars b_1, ..., b_m in the linear sum of the active variables nvars pointer to number of variables in the linear sum which will be overwritten by the number of variables in the linear sum corresponding to the active variables varssize available slots in vars and scalars array which is needed to check if the array are large enough for the linear sum w.r.t. active variables constant pointer to constant c in linear sum a_1*x_1 + ... + a_n*x_n + c which will chnage to constant d in the linear sum b_1*y_1 + ... + b_m*y_m + d w.r.t. the active variables requiredsize pointer to store the required array size for the linear sum w.r.t. the active variables mergemultiples should multiple occurrences of a var be replaced by a single coeff?

| SCIP_VAR ** | var, | ||
| SCIP_Real * | scalar, | ||
| SCIP_Real * | constant | ||
| ) |
transforms given variable, scalar and constant to the corresponding active, fixed, or multi-aggregated variable, scalar and constant; if the variable resolves to a fixed variable, "scalar" will be 0.0 and the value of the sum will be stored in "constant"; a multi-aggregation with only one active variable (this can happen due to fixings after the multi-aggregation), is treated like an aggregation; if the multi-aggregation constant is infinite, "scalar" will be 0.0
- Returns

gets strong branching information with previous domain propagation on column variable
Before calling this method, the strong branching mode must have been activated by calling SCIPstartStrongbranch(); after strong branching was done for all candidate variables, the strong branching mode must be ended by SCIPendStrongbranch(). Since this method applies domain propagation before strongbranching, propagation has to be be enabled in the SCIPstartStrongbranch() call.
Before solving the strong branching LP, domain propagation can be performed. The number of propagation rounds can be specified by the parameter maxproprounds.
- 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
scipis in one of the following stages:
- Warning
- When using this method, LP banching candidates and solution values must be copied beforehand, because they are updated w.r.t. the strong branching LP solution.
- Parameters
-

| SCIP_RETCODE SCIPchgVarLbLazy | ( | SCIP * | scip, |

| SCIP_Real | lazylb | ||
| ) |
changes lazy lower bound of the variable, this is only possible if the variable is not in the LP yet
Lazy bounds are bounds that are already enforced by constraints and the objective function. Setting a lazy lower bound has the consequence that for variables which lower bound equals the lazy lower bound, the lower bound does not need to be passed on to the LP solver. This is especially useful in a column generation (branch-and-price) setting.
- Attention
- If the variable has a global lower bound below lazylb, then the global lower bound is tightened to lazylb by a call to SCIPchgVarLbGlobal().
- 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
scipis in one of the following stages:

From a given equality a*x + b*y == c, aggregates one of the variables and removes it from the set of active problem variables. This changes the vars array returned from SCIPgetVars() and SCIPgetVarsData(), and also renders the arrays returned from the SCIPvarGetImpl...() methods for the two variables invalid. In the first step, the equality is transformed into an equality with active problem variables a'*x' + b'*y' == c'. If x' == y', this leads to the detection of redundancy if a' == -b' and c' == 0, of infeasibility, if a' == -b' and c' != 0, or to a variable fixing x' == c'/(a'+b') (and possible infeasibility) otherwise. In the second step, the variable to be aggregated is chosen among x' and y', prefering a less strict variable type as aggregation variable (i.e. continuous variables are preferred over implicit integers, implicit integers over integers, and integers over binaries). If none of the variables is continuous, it is tried to find an integer aggregation (i.e. integral coefficients a'' and b'', such that a''*x' + b''*y' == c''). This can lead to the detection of infeasibility (e.g. if c'' is fractional), or to a rejection of the aggregation (denoted by aggregated == FALSE), if the resulting integer coefficients are too large and thus numerically instable.
The output flags have the following meaning:
- infeasible: the problem is infeasible
- redundant: the equality can be deleted from the constraint set
- aggregated: the aggregation was successfully performed (the variables were not aggregated before)
- 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.

- This method can only be called if

| ) |
check if variable pseudo-costs have a significant difference in location. The significance depends on the choice of clevel and on the kind of tested hypothesis. The one-sided hypothesis, which should be rejected, is that fracy * mu_y >= fracx * mu_x, where mu_y and mu_x denote the unknown location means of the underlying pseudo-cost distributions of x and y.
This method is applied best if variable x has a better pseudo-cost score than y. The method hypothesizes that y were actually better than x (despite the current information), meaning that y can be expected to yield branching decisions as least as good as x in the long run. If the method returns TRUE, the current history information is sufficient to safely rely on the alternative hypothesis that x yields indeed a better branching score (on average) than y.
- Note
- The order of x and y matters for the one-sided hypothesis
-
set
onesidedto FALSE if you are not sure which variable is better. The hypothesis tested then reads fracy * mu_y == fracx * mu_x vs the alternative hypothesis fracy * mu_y != fracx * mu_x.
- Returns
- TRUE if the hypothesis can be safely rejected at the given confidence level
- Parameters
-

This is useful to determine if past observations provide enough evidence to skip an expensive strong-branching step if there is already a candidate that has been proven to yield an improvement of at least threshold.
- Note
- use
clevelto adjust the level of confidence. For SCIP_CONFIDENCELEVEL_MIN, the method returns TRUE if the estimated probability to exceedthresholdis less than 25 %.
- See also
- SCIP_Confidencelevel for a list of available levels. The used probability limits refer to the one-sided levels of confidence.
- Returns
- TRUE if the variable pseudo-cost probabilistic model is likely to be smaller than
thresholdat the given confidence levelclevel.
- Parameters
-
scip SCIP data structure var variable x frac the fractionality of variable x threshold the threshold to test against dir branching direction clevel confidence level for rejecting hypothesis
