About

Guillermo Ricardo Simari is a pioneering researcher in artificial intelligence, with a primary focus on defeasible reasoning, argumentation, and multi-agent systems. His work bridges theoretical logic and practical robotics, most notably through the development of Defeasible Logic Programming (DeLP), a formalism that allows agents to reason with incomplete and contradictory information. Simari’s key contributions include the KheDeLP framework, which integrates DeLP into Khepera robots, enabling them to make robust decisions in dynamic environments. His 2010 paper on a BDI (Belief-Desire-Intention) architecture for high-level robot deliberation (19 citations) demonstrates how layered reasoning systems can guide autonomous soccer robots. Additionally, his 2008 work on decision rules and arguments in defeasible decision making (17 citations) provides flexible models for agent preference and policy change. With foundational papers like “An Application of Defeasible Logic Programming to Decision Making in a Robotic Environment” (14 citations), Simari has shaped how agents handle uncertainty and conflict. His research remains highly influential in robotics, AI ethics, and computational argumentation, inspiring new generations of researchers to explore the intersection of logic and autonomous decision-making.
