  bibo_abstract:
  - 'We consider directed graphs where each edge is labeled with an integer weight
    and study the fundamental algorithmic question of computing the value of a cycle
    with minimum mean weight. Our contributions are twofold: (1) First we show that
    the algorithmic question is reducible to the problem of a logarithmic number of
    min-plus matrix multiplications of n×n-matrices, where n is the number of vertices
    of the graph. (2) Second, when the weights are nonnegative, we present the first
    (1+ε)-approximation algorithm for the problem and the running time of our algorithm
    is Õ(nωlog3(nW/ε)/ε),1 where O(nω) is the time required for the classic n×n-matrix
    multiplication and W is the maximum value of the weights. With an additional O(log(nW/ε))
    factor in space a cycle with approximately optimal weight can be computed within
    the same time bound.@eng'
