such a particular trace may not be scheduled for execution. Thus it is useful to compute the probability of executing the trace. Our probabilistic model of real-time systems requires that for each transition, the period
An algorithm is described that factors L within time (N ℒ) 0 (n 4) where ℒ is the bit size of L. Moreover, a bound N ≤ exp((ℒ2 n) 2 n) is obtained. We also exhibit a polynomial time algorithm for calculating the greatest common (right) divisor of a family of ...

Abstract This paper considers 2-regions of grid cubes and proposes an algorithm for calculating the number of tunnels of such a region. The graph-theoretical algorithm proceeds layer by layer; a proof of its correctness is provided, and its time complexity is also given....
Topcoder Open 2011 started recently. This weekend was the first qualification round of the algorithm competition. I had an interesting experience during it, which I want to share. The second problem was not that hard, though my solution seems to be too stupid for it. You can check out the...
One possible idea is to establish an immediate connection between eigenvectors and matrix elements. If this kind of connection can be figured out, it may be an appealing method for matrix diagonalization. Certainly, it is not easy to obtain the possible connection, because few precedents can be ...
If space complexity is an issue, they may be preferable. However, my findings are that the overhead of implementing the algorithm with a more complex data structure results in a slower overall runtime. Meanwhile, space concerns are not relevant with most "realistic" datasets. There are still ...

Exploring the special structure of these Markov chains, we are able to develop an efficient algorithm to compute the degree distribution numerically. The complexity of our algorithm is O(t^2), where $t$ is the number of time steps for adding new nodes. We use three examples to demonstrate ...
