# What is the toolkit that implements Cost sensitive Support Vector Machine?

I need implementation of cost sensitive support vector machine. The cost is different for each training example (unlike each class). So problem is to solve $max_\alpha$ $-1/2 \sum_{i,j} \alpha_i\alpha_jY_iY_jK(X_i,X_j) + \sum_i \alpha_i$ s.t. $0 <= \alpha_i <= c_i \forall i$ So are there any implementation (like LIBSVM, SVMlight) available to implement such SVM (where cost is different for each training point)?
