    "abstract": "We calculate ground-state properties of a many-quark system in the\nstring-flip model using variational Monte Carlo methods. The many-body\npotential energy of the system is determined by finding the optimal grouping of\nquarks into hadrons. This (optimal) assignment problem is solved by using the\nstochastic optimization technique of simulated annealing. Results are presented\nfor the energy and length-scale for confinement as a function of density. These\nresults show how quarks clustering decreases with density and characterize the\nnuclear- to quark-matter transition. We compare our results to a previously\npublished work with a similar model which uses, instead, a pairing approach to\nthe optimization problem.",
