Randomized competitive analysis for two server problems
Summary: We prove that there exists a randomized online algorithm for the 2-server 3-point problem whose expected competitive ratio is at most 1.5897. This is the first nontrivial upper bound for randomized \(k\)-server algorithms in a general metric space whose competitive ratio is well below the corresponding deterministic lower bound \((= 2\) in the 2-server case).
