Do not keep the arrays created by SCIPparseVarsPolynomial around, since they use buffer memory that is intended for short term use only.

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).
scip is in one of the following stages:
| scip | SCIP data structure |

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

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().

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:

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.
onesided to 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.| scip | SCIP data structure |
