Algorithm to enable the functionality of saving isolation MVA output in a RelationTable for SL

Tommaso Fulghesu requested to merge sl-algo-isolation into 2025-patches

Dependencies

Description

Implementation of the algorithm that creates RelationTable used by SL WG with the isolation MVA. The algorithm is used at the sprucing stage to remove duplicated pions persisted, as well as offline for ranking the extra tracks on the basis of their MVA score

Input: container of B^{*+}, container of signal candidates and F.MVA functor Output: Relation table <signal, extra track, MVA output>.

Addition of ELEMENT_AT_INDEX functor with proper tests

  • Tested in Rec, Moore, DV
