 2010-02-01 12:55:28 +00:00
Bernd Gärtner 4cdb07ecc3 last homegrown iterator replaced by boost-based solution 2008-10-23 14:31:10 +00:00
Bernd Gärtner b5a2bb1fec qp_x[i] -> *(qp_x+i) throughout, for all user-duplied iterators 2008-10-09 13:07:49 +00:00
Bernd Gärtner 3c686beb36 some more operator[]-related ad-hoc fixes for Polytope_distance_d 2008-10-09 10:06:21 +00:00
Bernd Gärtner c522b485c5 -some fixes to account for result of operator[] only being convertible to value type (at some point, this should sytematically be addressed by removing all occurrences of [] in the QP_solver code) 2008-10-09 09:42:02 +00:00
Bernd Gärtner 907223b777 First Boost 1.33.1 workaround (maybe others will be necessary as well) 2008-09-29 09:03:20 +00:00
Bernd Gärtner 081110184f - some homemade iterators replaced by boost variants 2008-07-31 20:55:38 +00:00
Bernd Gärtner 8612c935be - fixes to cope with removal of CGAL's funtional.h 2008-07-31 18:56:21 +00:00
Sylvain Pion 79864c0c8e Remove Arity_tag. 2008-07-22 12:29:01 +00:00
Sylvain Pion 2eb0d8f9e9 certainly() -> possibly(). 2008-07-14 11:16:41 +00:00
Sylvain Pion 9d7a609ff2 Make assertions trigger an error only for *certain* conditions (using CGAL::certainly()). 
This is useful for interval arithmetic code.
(replay of r44002 with the header order hopefully fixed)
 2008-07-10 21:49:17 +00:00
Sylvain Pion 2b4ebf01f7 Undo r44002 as it's buggy 2008-07-06 20:47:29 +00:00
Sylvain Pion 514a17ad4f Improve the interaction of assertions and interval computations. 
Things like "CGAL_assertion(denominator != 0)" produced assertion failures for no gain.
So now, the assertion is triggered only if the condition is certain, using CGAL::certainly().
That is, change the following in all assertion files :
  ((EX)?(static_cast<void>(0)): ::CGAL::assertion_fail( # EX , __FILE__, __LINE__))
to :
  (CGAL::certainly(EX)?(static_cast<void>(0)): ::CGAL::assertion_fail( # EX , __FILE__, __LINE__))
 2008-07-06 17:05:47 +00:00
Sylvain Pion d49e006c53 Remove default argument "0" to calls to assertion_fail() et al, 
as the default is now the empty string "".
It should fix the problem that we have lost the assertion messages
(seeing "what():  basic_string::_S_construct NULL not valid" instead),
for packages that use package-specific assertion macros.
 2007-12-21 21:58:27 +00:00
Bernd Gärtner b0cbc0defa - cosmetic output fix 2007-05-05 07:57:23 +00:00

  is an option to trigger a self-check
 2007-04-25 01:19:38 +00:00
Bernd Gärtner 060f6bf342 - minor refactoring; test_solver now also calls the interface

  be properly tested)
- added QSCORPIO as interesting additional example

Bernd Gärtner ce80f2f8db - _from_pointer models removed (they are useless as well) 
- fixed and added more examples, and referred to them from manual
 2007-04-14 15:39:55 +00:00
Bernd Gärtner 890c5d0fed - in Quadratic_program model, default bounds can now be configured, 
and there are some tests that cover this
 2007-04-13 16:12:08 +00:00
Bernd Gärtner 6ba585a7b1 - forgot that file (it's only a changed comment) 2007-04-12 14:51:36 +00:00
Bernd Gärtner 62f0ca4473 - manual:

- code:
	- renamed some QP_solution methods to make them more accessible
 2007-04-12 14:50:16 +00:00
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:

        - adapted to above changes
 2007-04-11 15:48:19 +00:00

 2007-04-03 14:54:38 +00:00
Bernd Gärtner 4cbbedf839 - missing const added 
- first_qp fixed to provide 2D instead of D
 2007-04-03 10:05:43 +00:00
Bernd Gärtner a971b7db8a - sparse mps readers added 
- minor fix in print routine
- output for mps instances deleted (it's replaced by the general template)
 2007-04-03 07:14:06 +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

     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
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

the actual problem
 2007-02-15 14:21:44 +00:00
Bernd Gärtner 1ecc6a24f2 - redundant friend removed; iterators now returned as "const Iterator" in the 
hope of pleasing Menelaos' debugged g++ platform
 2007-02-13 12:18:05 +00:00
Bernd Gärtner 7bbcbc2f31 fixes of small errors detected on various platforms 2007-02-12 08:41:50 +00:00

 2007-01-24 17:16:05 +00:00
Laurent Saboret 9d0d302a87 Fixed svn properties of whole trunk 2006-12-18 09:37:55 +00:00
Michael Hemmer 0257a65d7b replaced: 
CGAL::exact_division(..) -> CGAL::integral_division
 2006-11-17 08:56:52 +00:00
Michael Hemmer 085f9c5144 CGAL::exact_division -> CGAL::integral_division 2006-11-06 15:51:58 +00:00
Bernd Gärtner a949180978 introduced cast of qp_A[j] to A_column for cases where we get a proxy only 2006-11-01 11:57:09 +00:00
Bernd Gärtner aeb1213f4c - Free models added; 
- figures/program for closest point in intersection of halfspaces
 2006-10-27 14:07:45 +00:00
Bernd Gärtner 43d3e1b6bc important variables doc 2006-10-21 17:02:31 +00:00
Bernd Gärtner 503940b105 point in convex hull example added (examples+doc) 2006-10-21 15:25:32 +00:00
Bernd Gärtner d1c7c0d1f0 next user manual round 2006-10-19 20:07:04 +00:00
Bernd Gärtner b1994690c6 first part of usr manual; renamed functionality (QP->Quadratic_program...) 2006-10-19 17:47:58 +00:00
Bernd Gärtner 100bed9764 - minor documentation fix (c -> c_aux in is_sol_opt_for_aux_problem()) 2006-09-28 18:32:44 +00:00
Bernd Gärtner af94b11eb7 - ET/Quotient<ET> access to variable values/certicficates 2006-09-28 17:32:25 +00:00
Bernd Gärtner 561f2650f3 - introduced iterator for optimality certificate; the validity check 
is using it now
 2006-09-28 16:50:59 +00:00
Bernd Gärtner 6a05b09d69 - Unbounded_direction_iterator refactored; it now uses the 
Transform_diff_const_iterator
 2006-09-28 16:04:06 +00:00
Bernd Gärtner 68fc833cb5 - Is-symmetric tag removed; now all input is assumed to be symmetric. 
Reason: the tag is unecessary, and allowing non-symmetric input only
  allows the user to enter redundant information
 2006-09-28 14:29:33 +00:00
Bernd Gärtner a52c3881b6 - tag "Has_equalities_only_and_full_rank" removed; this is now handled 
dynamically in the code. Reason: this tag is difficult to explain to
  the user, does not have any effect on the interface, and is not very
  costly to dispatch dynamically
 2006-09-28 10:30:04 +00:00
Bernd Gärtner 631f1560f2 - vector O (original variable indices) removed and replaced by 
proper iterator
 2006-09-26 11:43:15 +00:00
Bernd Gärtner cb9694e886 - old internal type Double removed (Gmpzf takes over) 2006-09-26 10:07:07 +00:00
Bernd Gärtner 191f397d13 - basic interface for QP_solution enhanced; interface types and names 
are now consistently only introduced in QP_solution, while the virtual
  functions in QP_solver_base are implementation-centered
 2006-09-26 09:54:39 +00:00
