Cyclic Peptide Sequencing Problem (Cyclic Peptide Sequencing Problem)

Description

Given an experimental $MS^3$ spectrum $S$, find a cyclic peptide $P$ maximizing the number of shared masses between $S$ and the theoretical spectrum of $P$.

Parameters

$n$: size of peptide, in daltons

$m$: number of elements in experimental spectrum
