adds constraint to the given node (and all of its subnodes), even if it is a global constraint; It is sometimes desirable to add the constraint to a more local node (i.e., a node of larger depth) even if the constraint is also valid higher in the tree, for example, if one wants to produce a constraint which is only active in a small part of the tree although it is valid in a larger part. In this case, one should pass the more global node where the constraint is valid as "validnode". Note that the same constraint cannot be added twice to the branching tree with different "validnode" parameters. If the constraint is valid at the same node as it is inserted (the usual case), one should pass NULL as "validnode". If the "validnode" is the root node, it is automatically upgraded into a global constraint, but still only added to the given node. If a local constraint is added to the root node, it is added to the global problem instead.

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).

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:

branches on a variable x using a given value x'; for continuous variables with relative domain width larger epsilon, x' must not be one of the bounds; two child nodes (x <= x', x >= x') are created; for integer variables, if solution value x' is fractional, two child nodes are created (x <= floor(x'), x >= ceil(x')), if x' is integral, three child nodes are created (x <= x'-1, x == x', x >= x'+1)

n-ary branching on a variable x using a given value Branches on variable x such that up to n/2 children are created on each side of the usual branching value. The branching value is selected as in SCIPbranchVarVal(). The parameters minwidth and widthfactor determine the domain width of the branching variable in the child nodes. If n is odd, one child with domain width 'width' and having the branching value in the middle is created. Otherwise, two children with domain width 'width' and being left and right of the branching value are created. Next further nodes to the left and right are created, where width is multiplied by widthfactor with increasing distance from the first nodes. The initial width is calculated such that n/2 nodes are created to the left and to the right of the branching value. If this value is below minwidth, the initial width is set to minwidth, which may result in creating less than n nodes. Giving a large value for widthfactor results in creating children with small domain when close to the branching value and large domain when closer to the current variable bounds. That is, setting widthfactor to a very large value and n to 3 results in a ternary branching where the branching variable is mostly fixed in the middle child. Setting widthfactor to 1.0 results in children where the branching variable always has the same domain width (except for one child if the branching value is not in the middle).

Referenced by collectSolution(), and printValue(). Checks, if an iteratively updated value is reliable or should be recomputed from scratch. This is useful, if the value, e.g., the activity of a linear constraint or the pseudo objective value, gets a high absolute value during the optimization process which is later reduced significantly. In this case, the last digits were canceled out when increasing the value and are random after decreasing it. We do not consider the cancellations which can occur during increasing the absolute value because they just cannot be expressed using fixed precision floating point arithmetic, anymore. In order to get more reliable values, the idea is to always store the last reliable value, where increasing the absolute of the value is viewed as preserving reliability. Then, after each update, the new absolute value can be compared against the last reliable one with this method, checking whether it was decreased by a factor of at least "lp/recompfac" and should be recomputed.
