Abstract: Since the seminal paper on load balancing by Ron Graham in 1960's, parallel machine scheduling, served as the very first problem in approximation algorithms of combinatorial optimization, has attracted a great attention. The improvement on load balancing has also witnessed the birth and grow of the research field. In this paper we will present a brief state-of-art of this fundamental problem. In particularly we will introduce several achievements made by our group, which offer some insights on the approximability and hardness from different angles. A couple of potentially interesting questions will be posed as well.

Key words: combinatorial optimization, scheduling, hardness, approximation algorithms, online algorithms
