Integrating ILP and SMT for Shortwave Radio Broadcast Resource Allocation and Frequency Assignment
2017
Shortwave radio broadcasting is the principal way for broadcasting of voice in many countries. The broadcasting quality of a radio program is determined not only by the parameters of the transmission device, but also by the radio frequency. In order to optimize the overall broadcasting quality, it is desirable to designate both devices and frequencies to radio programs, subject to various constraints including the non-interference of radio programs. In this paper, we propose a two-phase approach to this constrained optimization problem. It integrates ILP and SMT solving, as well as a local search algorithm. These methods are evaluated using real data, and the results are promising.
