Improved Routing Strategies with Succinct Tables
In designing a routing scheme for a communication network it is desirable to use as short as possible paths for routing messages, while keeping the routing information stored in the processors’ local memory as succinct as possible. The efftciency of a routing scheme is measured in terms of its stretch factor-the maximum ratio between the cost of a route computed by the scheme and that of a chea...
متن کاملImproved Bounds for Sampling Contingency Tables
We study the problem of sampling contingency tables (nonnegative integer matrices with specified row and column sums) uniformly at random. We give an algorithm which runs in polynomial time provided that the row sums ri and the column sums cj satisfy ri (n 3/ m log m), and cj (m 3/ n log n). This algorithm is based on a reduction to continuous sampling from a convex set. The same approach was t...

متن کاملSpinal Hansens with Pseudo Syringomyelitic Form
Spinal cord involvement is rare in leprosy but not unknown. We document an interesting case of a 56 year old male presented with progressive weakness of all four limbs with gross wasting of limb muscles and multiple painless trophic ulcers over the hands and legs. Examination revealed pan sensory loss in glove and stock distribution with suspended sensory loss for pain and temperature over the ...
