Inheritance diagram for ConicBundle::NNCBoxSupportModification:
Public Member Functions | |
Constructors and initialization | |
| NNCBoxSupportModification (CH_Matrix_Classes::Integer var_olddim=0, const CBout *cb=0, int incr=-1) | |
| constructor, calls modification constructor | |
| void | clear (CH_Matrix_Classes::Integer var_olddim) |
| reset modifications to an unmodified object currently having var_olddim variables, calls Modification::clear | |
| virtual | ~NNCBoxSupportModification () |
Routines for adding modifications | |
| int | add_append_vars (CH_Matrix_Classes::Integer append_dim, const CH_Matrix_Classes::Matrix *append_lb, const CH_Matrix_Classes::Matrix *append_ub) |
| append append_dim new variables to the box function | |
| int | add_reassign_vars (const CH_Matrix_Classes::Indexmatrix &map_to_old) |
| reassign the variables as given in map_to_old, calls Modification::add_reassign_vars | |
| int | add_delete_vars (const CH_Matrix_Classes::Indexmatrix &del_ind, CH_Matrix_Classes::Indexmatrix &map_to_old) |
| delete the variables indexed by del_ind; for each new index map_to_old returns the old one; calls Modification::add_delete_vars | |
Routines for applying the collected modifications | |
| int | apply_to_bounds (CH_Matrix_Classes::Matrix &lb, CH_Matrix_Classes::Matrix &ub) const |
| carry out the collected modifications on the given vectors of lower and upper bounds on the variables by calling Modification::apply_to_vars | |
Routines for querying properties of the collected modifications | |
| bool | no_modification () const |
| returns true if no modifications need to be executed except possibly an offset change for the ground set minorant | |
| int | set_append_to_old (bool append_only) |
| if set to true, no deletions/reassignments may be present or specified in the future, only appensions are allowed | |
| bool | append_to_old () const |
| returns true if this only contains appending operations and incorporating this is done with respect to the old dimension | |
| bool | no_additions_or_deletions_in_vars () const |
| returns true if no variables were added or deleted (allows permutations), false otherwise | |
| bool | deleted_variables_are_zero (const CH_Matrix_Classes::Matrix &oldpoint) const |
| returns true if all entries deleted in oldpoint (must be a vector of length old_vardim()) are 0, false otherwise | |
| bool | new_variables_are_zero (const CH_Matrix_Classes::Matrix &newpoint) const |
| returns true if all entries in newpoint (must be a vector of length new_vardim()) that correspond to new variables have value 0 and false otherwise | |
| bool | mapped_variables_are_equal (const CH_Matrix_Classes::Matrix &newpoint, const CH_Matrix_Classes::Matrix &oldpoint) const |
| returns true if the values in newpoint (must be a vector of length new_vardim()) that correspond to old variables match the old values stored in oldpoint (must be a vector of length old_vardim()) and false otherwise | |
Routines implementing the abstract OracleModifcation messages | |
| int | get_old_vardim () const |
| returns the number of variables before modification | |
| int | get_new_vardim () const |
| returns the number of variables once all stored modifications have been performed | |
| int | get_appended_vardim () const |
| returns the number of variables that are appended (due to later reassignmentds they may no longer be located at the end) | |
| const int * | get_map_to_old_variables () const |
| returns null if there are no index changes, otherwise the Indexmatrix pointed to is a vector whose i-th entry holds the old index of the new i-th variable (injective!), index values exceeding old_vardim() refer to newly appended variables | |
| int | incorporate (const OracleModification &m) |
| incorporate the OracleModification m (it should only contain variable changes, but this is not checked!) into this one; calls Modification::incorporate | |
| OracleModification * | new_initial_oraclemodification (int old_var_dim) const |
| returns a new object on the heap, that allows to incorporate this but starts off from a function whose input argument dimension is old_var_dim | |
| int | add_append_variables (int append_dim) |
| append append_dim further variables at the end of the argument vector (without effect on the box function, i.e., lower and upper bounds are set to 0) | |
| int | add_reassign_variables (int new_dim, const int *map_to_old_indices) |
| reorder and resize the variables as given by the first new_dim entries of map_to_old_indices; each former index may appear at most once in this list, so new_dim < get_new_vardim() | |
Routines for retrieving the detailed collected modifications | |
| CH_Matrix_Classes::Integer | old_vardim () const |
| returns the number of variables before modification (given on initialization) | |
| CH_Matrix_Classes::Integer | new_vardim () const |
| returns the number of variables once all stored modifications have been performed | |
| CH_Matrix_Classes::Integer | appended_vardim () const |
| returns the number of variables that are appended (due to later reassignmentds they may no longer be located at the end) | |
| const CH_Matrix_Classes::Indexmatrix * | map_to_old_variables () const |
| returns null if there are no index changes, otherwise the Indexmatrix pointed to is a vector whose i-th entry holds the old index of the new i-th variable (injective!), index values exceeding old_vardim() refer to newly appended variables | |
| const CH_Matrix_Classes::Indexmatrix * | deleted_var_indices () const |
| returns null if there were no deletions, otherwise the Indexmatrix pointed to is a vector holding the deleted old variable indices in increasing order | |
| const CH_Matrix_Classes::Indexmatrix * | new_var_indices () const |
| returns null if no variables were added, otherwise the Indexmatrix pointed ato is a vector holding the new indices of the new variables in increasing order | |

Detailed Description
Collects modifications for NNCBoxSupport for appending, deleting or reassigning variables and respective upper and lower bounds.
This class is implemented by restricting the possibilities of ConicBundle::Modification to the operations involving variables, so all routines simply call those of Modification. See the description there for usage and default values. The default value is 0 for lower or upper bounds that are not given explicitly.
The documentation for this class was generated from the following file:
