    We design a 1.75-approximation algorithm for a special case of scheduling parallel machines to minimize the makespan, namely the case where each job can be assigned to at most two machines, which the same processing time on either machine. We also show that even for this special case it is $NP$-hard to compute better than 1.5 approximation.

    Článek navrhuje a analyzuje algoritmy a dolní odhady pro vyvažování grafů. Jde o speciální případ rozvrhování nezávislých paralelních počítačů.
