Approximating Optimisation Solutions for Travelling Officer Problem with Customised Deep Learning Network

no code implementations8 Mar 2019 Wei Shao, Flora D. Salim, Jeffrey Chan, Sean Morrison, Fabio Zambetta

Deep learning has been extended to a number of new domains with critical success, though some traditional orienteering problems such as the Travelling Salesman Problem (TSP) and its variants are not commonly solved using such techniques.

For an operational mode which balances purity and completeness ($p_{\rm min}=0. 28$) we recover a purity of $96. 81\pm0. 39\%$ ($99. 30\pm0. 14\%$ for quasars with $z \geq 2. 1$) and a completeness of $96. 83\pm0. 30\%$ ($98. 42\pm0. 15\%$ for quasars with $z \geq 2. 1$).
