18e5da6297 Remove unused variable and add copy constructor. 2012-09-01 16:31:14 +12:00

7583db5a1e Add an alternative solver to lp_solve. The solver based on Ingo's active set solver but is able to handle arbitrary hard and soft constraints. The advantage to lp_solve is that the active set solver can optimize variable in respect to a quadratic objective function. This makes it possible to minimise the quadratic derivation to a desired value e.g. \Sum_i(x_i - x_{i,pref})^2 -> min.
The solver part has been refactored in this way that both solver can be used with the same layout specifications. The active set solver is default now; the performance is not as good as lp_solve, though.

5bced18eab ALM/linprog patch by Christof Lutteroth:
* Got rid of class ObjFunctionSummand. Both the constraint summands and
  the objective function summands are now stored using class Summand.
* Some method names are more BeOS compliant now: SetX instead of ChangeX.
* linprog test code now uses new AddConstraint methods.
* CalculateMinSize and CalculateMaxSize did not free the memory they
  allocated.
* Removed inappropriate setter and getter methods.
* Memory allocated in class Constraint is freed now.
* Other small changes.

0306945545 Patch by Christof Lutteroth:
* copyright headers for the files of the libraries linprog and alm
* new class Summand for representing summands in a linear constraint
* merged class SoftConstraint into class Constraint; Constraint now
  supports both soft and hard constraint functionality
* new AddConstraint methods in class LinearSpec for directly setting
  constraints with 1 to 4 summands
* code cleanups by using aforementioned AddConstraint methods
* a new very simple test application for alm
* some style corrections
