Bernd Gärtner 4214cf44b4 - simplification: some redundant models removed 2007-04-12 07:48:28 +00:00
Bernd Gärtner a2712eb429 - various refactorings: 
- mps reader is now derived from a model that allows to set
	  up and manipulate a program entrywise
	- old copying models removed
        - free models removed (they are utterly useless)
        - a() -> get_a() etc.
        - the solver can now solve problems with no variables :-)
- manual:
        - added maker pages
        - adapted to above changes
 2007-04-11 15:48:19 +00:00
Bernd Gärtner eacca3f01d - the order of QMATRIX entries changed 2007-04-11 07:12:26 +00:00
Bernd Gärtner 6a7eed25d7 - switched back to nonverbose test_MPS 2007-04-03 17:57:59 +00:00
Bernd Gärtner 05bb54506f - made certificate examples work directly with the iterators rather 
than copying their ranges
 2007-04-03 17:49:14 +00:00
Bernd Gärtner 8e41774983 - added performance note to solving functions doc 
- changed unbounded direction w so that x + tw is the unbounded ray
- aded certificate iterators to QP_solution
- added example programs that demonstrate the certificates
- fixed examples so that 2D instead of D is given

 2007-04-03 07:14:06 +00:00
Bernd Gärtner 6b13cebe20 - maintainer file 2007-04-02 19:21:54 +00:00
Bernd Gärtner 0b043a97e6 - committed test_random_qp; it now also solves the programs using 
their NQP, LP, NLP interfaces
 2007-04-02 17:52:18 +00:00
Bernd Gärtner 2d225d4184 - added doc for QP_models 2007-04-02 14:05:46 +00:00
Bernd Gärtner 9f5e838e6f - added a farkas-Lemma proof of infeasibility 
- added test with random small QP's
- fixed some bugs discovered by this:
   - output routine for programs is now printing symmetric D
   - internal comparison routine is now ignoring bound value if it
     was specified as infinite
   - fixed sign error in subrotuine of ratio_test
   - removed constant term from consideration in phase I
 2007-04-02 10:01:50 +00:00
Bernd Gärtner f0ebdcf4af - fixed tesuite so that filtered pricing strategies are only used 
if input type is double
- *always* run the tests if input type is rational, since file types
  double/int/rational all convert to it
 2007-03-30 18:25:09 +00:00
Andreas Fabri c7e831b9ac Removed unused arguments 2007-03-27 07:49:33 +00:00
Bernd Gärtner 290d0e7e1f - fixed all occurrences of qp_A[i][j], qp_D[i][j] (qp_A[i], qp_D[i] are in 
general only convertible to the appropriate iterator types, and so the
  above will not work. The fix is to use (*(qp_A + i))[j]
 2007-03-23 10:57:07 +00:00
Bernd Gärtner 51b3b30f78 - copying models now have default/copy-constructors and assignment ops 
- test (and fixed) access to upper-diagonal entries in D
- MPS read/write disagreement now only triggers warning (small differences
  may be ok if floating point numbers are used)
 2007-03-23 10:20:03 +00:00
Bernd Gärtner 8a7a6a899e - internal qp_D now represents 2*D 2007-03-22 13:45:07 +00:00
Bernd Gärtner a82ea6875e Is_in_standard_form -> Is_nonnegative (like in interface) 2007-03-22 10:10:57 +00:00
Bernd Gärtner 00657e993b - is_valid made private and integrated into QP_solver constructor (it may use 
QP data that are no longer available after the constructor call)
- fixed copying models to only copy entries of D on/below the diagonal
- fixed are_equal_qp function to only access entries of D on/below the diagonal
 2007-03-22 09:41:04 +00:00

Bernd Gärtner 48b08c927a - added new models that copy the data and integrated them into testsuite 2007-03-19 17:02:50 +00:00
Bernd Gärtner 3992a4840c - integrated MPS print function into test suite 
- cleaned up QP_functions by putting internal stuff into nested namespace
