CompressiveSampling MP is another influential reconstruction algorithm proposed by D. Needell after ROMP. CoSaMP is also an improvement over OMP. Each iteration selects multiple atoms. In addition to the selection criteria for atoms, it differs from ROMP in that ROMP's already selected atoms are retained for each iteration, and CoSaMP selects each iteration. The atom may be abandoned in the next iteration.
