Reproducibility Variable Result LLM Response
Research Type Experimental 7 Experimental Evaluation We demonstrate the efficiency of our algorithms through numerical experiments. We use CPLEX (version 12.6) to solve the linear program. All computations are performed on a machine with a 3.2GHz quad core CPU and 16GB memory. All results are averaged over 30 randomly generated instances. All random planar graphs are generated by the grid model with random edges (Peng et al. 2014), which samples an L ˆ W square grid where horizontal/vertical edges between neighbors are generated with probability p, and diagonal ones with q.

Pseudocode Yes Algorithm 1: IGRS and Algorithm 2: BRps,bsq
Open Source Code No The paper does not provide any statement or link indicating the release of open-source code for the described methodology.
Open Datasets Yes We also evaluate our approach on the road network of the whole Manhattan island of New York as shown in Figure 2(j). In this network, there are 702 nodes with 1,216 links extracted from OSM (www.openstreetmap.org).
Dataset Splits No The paper describes generating random graph instances and selecting initial positions, but does not specify training, validation, or test dataset splits (e.g., 80/10/10 split) or cross-validation setup for any dataset.
Hardware Specification Yes All computations are performed on a machine with a 3.2GHz quad core CPU and 16GB memory.
Software Dependencies Yes We use CPLEX (version 12.6) to solve the linear program.
Experiment Setup Yes By default, L W 5, pp, qq p0.5, 0.1q, horizon tmax L, |Ve| 10, and m 4.
