Detailed Description
The CsdpSolver class solves problems using Csdp.
- Version
- 1.0, 05/26/2014
- Since
- OS 2.8
- Remarks
- this class takes an OSiL instance and optimizes it using the COIN-OR Csdp solver

Member Function Documentation
|
virtual | |||||||||||||
solve results in an instance being read into the Csdp data structures and optimized
Implements DefaultSolver.
Definition at line 717 of file OSCsdpSolver.cpp.
|
virtual | |||||||||||||
The implementation of the virtual functions.
- Returns
- void.
If we're using unsigned shorts, make sure that the problem isn't too big.
Allocate space for the C matrix (A0).
Handle diagonal blocks and matrix blocks separately.
Allocate space for the constraints (again using 1-based indexing).
Null out all pointers in constraints.
Go through all of the blocks in each of the constraint matrices, and allocate space for the entries and indices.
initialize and allocate storage for the entries in this block of this constraint.
Implements DefaultSolver.
Definition at line 85 of file OSCsdpSolver.cpp.
|
virtual | |||||||||||||
The implementation of the virtual functions.
- Returns
- void.
Since CSDP provides no user interface for solver options other than reading them in from the file param.csdp (if this file exists) the only choice is to write the options to file so that they can be read back by the CSDP method initparams(), called from easy_sdp().
Note also that initial values are not treated here; there is the special method setInitialValues() that should be used for that purpose.
Implements DefaultSolver.

| void CsdpSolver::dataEchoCheck | ( | ) |
use this for debugging, print out the instance that the solver thinks it has and compare this with the OSiL file
