  • Numerical parallel approach to counting Hamiltonian cycles with Proth primes

    Counting the number of Hamiltonian cycles of a given graph can be formulated with higher order derivatives. Thus its value can be computed as the residue with complex floating numbers. But there are inevitable rounding errors in the conventional computation of the residue whereas the mathematical result is an integer value. In this paper, by use of the Proth primes that are represented by k . 2(n) + 1 for odd number k, algorithms of the residue with modular arithmetics are proposed in order to compute the exact integer result. It is shown that they are naturally executed on parallel processors by partitioning the summation of the residue, so that, with q (<= 2(n)) processors, the time complexity is O(n(3)2(n)/q) for each machine and O(log q) for summing up all the q partial sums.

    We developed educational materials to learn operation of GIS software, use of GIS-related instruments such as drones, creation of interactive Web maps, and other relevant things. Anybody can access the materials with a web browser, and the software packages and data used in the materials are free of charge. The materials underwent several updates based on feedbacks from users especially undergraduate students who took our classes. The online materials have been frequently accessed by various people, indicating that they contribute to the propagation of GIS. We analyzed educational effects and other scientific implications of the materials, and presented them in conferences and papers.
