◆ SCIPvarGetActiveRepresentatives()

SCIP_VAR **  vars,
SCIP_Real scalars,
int *  nvars,
int  varssize,
SCIP_Real constant,
int *  requiredsize,
SCIP_Bool  mergemultiples 
)

transforms given variables, scalars and constant to the corresponding active variables, scalars and constant

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; hence, if afterwards the required size is greater than the available slots (varssize), nothing happens; otherwise, the active variable representation is stored in the arrays.

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).

Parameters
setglobal SCIP settings
varsvariable array to get active variables
scalarsscalars a_1, ..., a_n in linear sum a_1*x_1 + ... + a_n*x_n + c
nvarspointer to number of variables and values in vars and scalars array

constantpointer to constant c in linear sum a_1*x_1 + ... + a_n*x_n + c
requiredsizepointer to store the required array size for the active variables

◆ SCIPvarFlattenAggregationGraph()

SCIP_RETCODE SCIPvarFlattenAggregationGraph ( SCIP_VAR var,
BMS_BLKMEM blkmem,
SCIP_SET set 
)

flattens aggregation graph of multi-aggregated variable in order to avoid exponential recursion later on

Note
After the flattening the multi aggregation might resolve to be in fact an aggregation (or even a fixing?). This issue is not resolved right now, since var->data.multaggr.nvars < 2 should not cause troubles. However, one may loose performance hereby, since aggregated variables are easier to handle.

Note, that there are two cases where SCIPvarFlattenAggregationGraph() is called: The easier one is that it is called while installing the multi-aggregation. in principle, the described issue could be handled straightforward in this case by aggregating or fixing the variable instead. The more complicated case is the one, when the multi-aggregation is used, e.g., in linear presolving (and the variable is already declared to be multi-aggregated).

By now, it is not allowed to fix or aggregate multi-aggregated variables which would be necessary in this case.

The same issue appears in the SCIPvarGetProbvar...() methods.

◆ SCIPvarMergeHistories()

void SCIPvarMergeHistories ( SCIP_VAR targetvar,

merge two variable histories together; a typical use case is that othervar is an image of the target variable in a SCIP copy. Method should be applied with care, especially because no internal checks are performed whether the history merge is reasonable

Note
Do not use this method if the two variables originate from two SCIP's with different objective functions, since this corrupts the variable pseudo costs
Apply with care; no internal checks are performed if the two variables should be merged
Parameters

Tries to aggregate an equality a*x + b*y == c consisting of two (implicit) integral active problem variables x and y. An integer aggregation (i.e. integral coefficients a' and b', such that a'*x + b'*y == c') is searched.

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.

performs second step of SCIPaggregateVars(): the variable to be aggregated is chosen among active problem variables x' and y', preferring a less strict variable type as aggregation variable (i.e. continuous variables are preferred over implicit integers, implicit integers or 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.

SCIP_RETCODE SCIPvarRemove ( SCIP_VAR var,

)

informs variable that it will be removed from the problem; adjusts probindex and removes variable from the implication graph; If 'final' is TRUE, the thorough implication graph removal is not performed. Instead, only the variable bounds and implication data structures of the variable are freed. Since in the final removal of all variables from the transformed problem, this deletes the implication graph completely and is faster than removing the variables one by one, each time updating all lists of the other variables.

Parameters
varproblem variable
blkmemblock memory buffer
cliquetableclique table data structure
setglobal SCIP settings
finalis this the final removal of all problem variables?

adds given implication to the variable's implication list, and adds all implications directly implied by this implication to the variable's implication list; if the implication is conflicting, the variable is fixed to the opposite value; if the variable is already fixed to the given value, the implication is performed immediately; if the implication is redundant with respect to the variables' global bounds, it is ignored
