Detailed Description

template<class InputType>
class shark::RemoveBudgetMaintenanceStrategy< InputType >

Budget maintenance strategy that removes a vector.

This is an budget strategy that simply removes one of the budget vectors. Depending on the flavor, this can be e.g. a random one, the smallest one (w.r.t. to 2-norm of the alphas)
