Inapproximability and Polynomial-Time Approximation Algorithm for UET Tasks on Structured Processor Networks
We investigate complexity and approximation results on a processor networks where the communication delay depends on the distance between the processors performing tasks. We then prove that there is no heuristic with a performance guarantee smaller than 4/3 for makespan minimization for precedence g...
