Claims a genetic algorithm with dynamic time warping and dynamic programming reconstructs sparse vehicle GPS to map links, provides Python code, and beats prior methods on Belgrade data (claimed "most accurate model for sparse GPS data"). Initial population is seeded by proximity to GPS points, fitness combines shortest-path DP and DTW similarity, three generations reach 95% of solutions (max 27 before tuning), subsequence clipping cuts mean runtime to 0.3s mean runtime.
