## Contribution

It presents a novel approach using simulated annealing for fragment identification, enhancing the analysis of isotope and hyper-nucleus production in transport models.

## Key findings

- Accurately predicts isotope yields and hyper-nucleus production.
- Demonstrates sensitivity of cluster formation parameters.
- Shows good agreement with experimental data.

## Abstract

We present a new approach to identify fragments in computer simulations of relativistic heavy ion collisions. It is based on the simulated annealing technique and can be applied to n-body transport models like the Quantum Molecular Dynamics. This new approach is able to predict isotope yields as well as hyper-nucleus production. In order to illustrate its predicting power, we confront this new method with experimental data and show the sensitivity on the parameters which govern the cluster formation.
