The anti-leakage matching pursuit (ALMP) algorithm can estimate harmonics and interharmonics mainly under noise and frequency deviations. The algorithm is based on the Matching Pursuit method, and its principal stage consists of solving a non-linear least squares problem.

The file almp.py contains the algorithms' implementation. The file signal_generator.py has functions to generate synthetic signals for analysis and a function for adding Gaussian white noise to signals. The file main.py has an example of using the ALMP algorithm.
