We perform an agent-based simulation where we model the interactions between particles as non-reciprocal, add movements from stochastic origins, and include multiplication and elimination mechanisms. We conclude by making a comparison with the ideal Lotka-Volterra model for population description. We find that our model exhibits oscillations in the populations, but with solutions outside the family of curves of the Lotka-Volterra equations. It is a more realistic model that exhibits the expected dynamics of a more general model of equations than the classical Lotka-Volterra.12 p.application/pdfengcc-by-nc-nd (c) Guevara, 2026http://creativecommons.org/licenses/by-nc-nd/4.0/Model de Lotka-VolterraMecànica estadísticaTreballs de fi de grauLotka-Volterra modelStatistical mechanicsBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
