Mehdi,

> I need to solve an LP (a set partitioning problem) starting from a given initial point, e.g. starting from a basis containing x_1, x_4, x_8. How is that possible? Are there any example codes of such type out there? 

	Construct a CoinWarmStartBasis object with the appropriate status for
your variables. Feed that to setWarmStart and then resolve.
