) | [inline] |
Assign the primal/dual vectors to be the warmstart information.
In this method the object assumes ownership of the pointers and upon return primal
and dual
will be a NULL pointers. If copying is desirable use the constructor.
NOTE: primal
and dual
must have been allocated by new double[], because they will be freed by delete[] upon the desructtion of this object...

Make it appear as if the warmstart was just created using the default constructor.

virtual CoinWarmStartDiff* CoinWarmStartPrimalDual::generateDiff | ( | const CoinWarmStart *const | oldCWS | ) | const [virtual] |
Generate a `diff' that can convert the warm start passed as a parameter to the warm start specified by this
.
The capabilities are limited: the basis passed as a parameter can be no larger than the basis pointed to by this
.
Reimplemented from CoinWarmStart.
virtual void CoinWarmStartPrimalDual::applyDiff | ( | const CoinWarmStartDiff *const | cwsdDiff | ) | [virtual] |
Apply diff
to this warm start.
Update this warm start by applying diff
. It's assumed that the allocated capacity of the warm start is sufficiently large.
