A new mixed-integer programming (MIP) approach has been developed for offline multiple change-point detection, framing the problem as a globally optimal piecewise linear fitting task. This method introduces strengthened MIP formulations with linear programming relaxations that offer integral projections onto segment-assignment variables, providing provably tighter relaxations than existing techniques. The framework is also extended to multi-dimensional piecewise linear models with shared change-points, and computational experiments show significant reductions in solution times compared to current state-of-the-art methods.
