 SMO algorithm for separable single-class SVM problem.

             long num_data,
             long tmax,
             double tolabs,

 tmax, tolabs, tolrel ... Define stopping conditions: 

    UB <= tolabs              ->  exit_flag = 1   Abs. tolerance.
    (UB-LB)/(LB+1) <= tolrel  ->  exit_flag = 2   Relative tolerance.
    t >= tmax                 ->  exit_flag = 0   Number of iterations.
 
 Alpha ... Lagrangians defining found decision rule. 
 UB ... Achieved upper bound on the optimal solution.
 LB ... Achieved lower bound on the optimal solution.
 t  ... Number of iterations.
 History ... Value of LB and UB wrt. number of iterations.
