In this paper, we propose an integer linear programming model whose solutions are the aperiodic rhythms tiling with a given rhythm A. We show how it can be used to define iterative algorithm that, period n, finds all which tile A and also efficiently check necessity of Coven-Meyerowitz condition (T2). To conclude, run several experiments validate time efficiency model.

this paper presents a framework for long term transmission expansion planning in competitive, electricity markets. transmission lines and phase shifters are taken into account as expansion options. maximization of the network users' benefits, with satisfying security constraints are considered as the criterion for transmission expansion planning. the elements of the objective function are the...
