B 0 s → K + K − and B 0 s → K 0 K̄ 0 Decays within Supersymmetry

We compute the supersymmetric (SUSY) contributions to the observables in B s → KK and B s → KK̄ decays. The hadronic parameters in the standard-model (SM) amplitudes are obtained from the B d → KK̄ decay using a recent approach that combines flavor SU(3) symmetry and a controlled input from QCD factorization. The latest experimental data for BR(B s → KK) is in agreement with the SM prediction. We...

Partial S(k-1, k, v)'s inducing Pk-decompositions of Kv

Let Pk be the path with k vertices and k − 1 edges, k ≥ 4. For every integer v, v ≡ 0 or 1 (mod 2(k − 1)) if k is odd or v ≡ 0 or 1 (mod k−1) if k is even, we produce a Pk-design (V,B) of order v such that no two blocks have k − 1 or k common vertices, i.e. (V,B) is a partial S(k − 1, k, v). AMS classification: 05B05.

Driver Scheduling using Genetic Algorithms with Embedded Combinatorial Traits by Ann S K Kwan , Raymond S K Kwan & Anthony Wren June 1997

The mathematical programming based approaches to driver scheduling have had most success, including the IMPACS and TRACS II systems developed by the authors and their associates. However there is scope for improvement in terms of computational efficiency, robustness, and capability to tackle large data sets. This paper describes ongoing research into using the Genetic Algorithm (GA) approach to...
