Researchers have developed an online learning algorithm designed to optimize load balancing in systems with heterogeneous service rates that are not initially known. This algorithm aims to route customers using the Shortest-Expected-Delay (SED) policy by carefully balancing empirical SED routing with mandatory exploration phases to ensure sufficient sampling of all servers. The proposed method guarantees finite regret, a departure from typical multi-armed bandit settings, and numerical experiments confirm its effectiveness, particularly in scenarios where forced exploration is beneficial.
