Abstract

For any fixed dimension d , the linear programming problem with n inequality constraints can be solved on a probabilistic CRCW PRAM with O ( n ) processors almost surely in constant time. The algorithm always finds the correct solution. With nd /log 2 d processors, the probability that the algorithm will not finish within O ( d 2 log 2 d ) time tends to zero exponentially with n . — Authors' Abstract
