Converting algorithms from iLCSoft to Gaudi Acronyms in the title and meaning: iLCSoft, common software framework for Linear Collider

Future collider experiments rely on well maintained software frameworks and algorithms to perform physics studies and detector optimization. ILCSoft developed software packages for the International Linear Collider (ILC) community which are used by ILC and CLIC, including a software framework and a set of algorithms that have been successfully used by these communities. The Key4hep project is building a consistent well-maintained common software stack used and developed by FCC, ILC, CLIC, CEPC. The software stack includes common packages for the Event Data Model (EDM), the Gaudi based software framework, detector simulation, event generation and algorithms. Key4hep integrates ILCSoft battle-tested algorithms to be used as part of the common software stack. To achieve this an EDM converter and algorithm wrapper to run with the common framework and interfaces (Gaudi) is provided. As this solution introduces overheads for the conversions, and several components are not natively Integrated with the common framework, Key4hep must undergo a conversion and modernization of the iLCSoft algorithms
