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
Bernd Gärtner e1ec6bd6af - in derivatives creation, changed order of mps-reading: int, double, rational 2006-09-26 08:24:04 +00:00
Bernd Gärtner 49cac0da8b - removed special handling of Gmpq from QP_models, since the read-from-float 
capability is now available in Gmpq.h
 2006-09-19 14:30:56 +00:00
Bernd Gärtner 2898e47b44 put test_solver output under version control to allow regression testing 2006-09-18 12:10:55 +00:00
Bernd Gärtner 6a21496393 - added sparse representation and handling of LP to MPS reader; make_zero_D is removed 2006-09-16 19:12:07 +00:00
Bernd Gärtner aff6bd05a5 - made first version of QP_solution 
- refactored QP_solver to have missing types / iterators from QP generated
- added normalization of variable values / solution
 2006-09-14 16:46:51 +00:00
Bernd Gärtner f9ff2cfb36 - added make_qp function (more will follow: make_lp, make_nonnegative_lp,...) 
- moved write_MPS out of QP_from_mps and made general
- introduced QP_solution as ref-counted wrapper for QP_solver pointers
 2006-09-13 21:10:11 +00:00
Bernd Gärtner 7464866235 - added QP models 
- refactored QP_solver to separate the QP, the ET and the Tags
- got rid of MPS.h, MPS.C (integrated into QP_models)
- added QP_functions.h to test full rank of QP
- added QP_solver diagnostics for friends to access
- removed ET type from MPS reader (was only needed for rank test, and now
  I'm using the new QP function for that -> faster and cleaner)
 2006-09-09 14:58:32 +00:00
Bernd Gärtner d0a6a430ce removed configurable row type, now CGAL::Comparison must be used 2006-09-05 12:32:25 +00:00
Bernd Gärtner 6d9fb3278d - adapted all pricing strategies to deal with nonstandard form 
- made pricing of a single variable a method in base class QP_pricing_strategy 
- added missing pricing strategy notification in enter_and_leave_variable()
 2006-09-05 11:45:44 +00:00
Bernd Gärtner 33cdafd438 - adapted to new type Gmpzf 
- fixed some possible sources of ambiguity: all arithmetic ops now
  have both operands of the same type
 2006-08-31 11:27:31 +00:00
Bernd Gärtner 0bd5d53953 replaced CGAL::Double by CGAL::MP_Float and removed all includes of Double 2006-08-25 14:06:31 +00:00
Bernd Gärtner 02144270f0 minor fix (initialization of constant term c0 was missing) 2006-08-25 08:34:32 +00:00
Bernd Gärtner 1d057b9e59 enhanced MPS parser. It can now handle 
- NAMEs with spaces
	- RANGES 
	- RHS entry for objective row (means: constant term in obj func)
enhanced QP_solver. It can now handle a constant term in obj func
 2006-08-24 14:12:24 +00:00
Bernd Gärtner 1a13222641 files updated from benchamrks repository 2006-08-24 13:31:32 +00:00
Bernd Gärtner b8b1810b58 - added some additional assertions 
- in write_MPS, 0's are now omitted
- added routine to read floating-point number in decimal format from MPS
- fixed two bugs that didn't have any effect (yet)
- commented out some expensive checks / long outputs in example programs
 2006-08-24 07:45:02 +00:00
