Particular attention is paid to the parallel solution of UBET by optimization techniques. The UBET approach, its formulation, and suitable parallel algorithms are presented, and discussions are made on the parallel algorithms for the UBET calculation and optimization processes. Results of the parallel algorithms on the DAP are evaluated in comparison with that of a serial approach on a mainframe computer. INTRODUCTION The Upper Bound El
