Heuristic branch-and-price for building long term trainee schedules. [PDF]
Branch-and-price is an increasingly important technique for solving large integer programming models. Staff scheduling has been a particularly fruitful area since these problems typically exhibit a decomposable structure.

THE RAY-METHOD: THEORETICAL BACKGROUND AND COMPUTATIONAL RESULTS
Croatian Operational Research Review, 2012 In our talk we present an algorithm for determining initial bound for the Branch and Bound (B&B) method. The idea of the algorithm is based on the use of the "ray" introduced in the "ray-method" developed for solving integer programming problems [13 ...

Electrochemical Doping for Absorption and Conductivity Tuning of P(NDI2OD‐T2) Films
Advanced Electronic Materials, EarlyView.Electrochemical doping of P(NDI2OD‐T2) films allows for tuning the degree of doping both in liquid electrolytes as well as in the solid state. The nature of the doped species is elucidated by UV–vis spectroscopy and accompanying DFT calculations. Correlations between maximum conductivities and the presence of mixed valence states, (specifically neutral/
