Causal, Strategic, and Combined Responsibility Attribution in Situation Calculus Concurrent Game Structures

AAAI 2026technical

Responsibility is a central concept in accountable decision making for multiagent systems. As modern AI systems grow in complexity and autonomy, there is a growing demand for them to address issues in AI ethics, prompting researchers to formalize responsibility from diverse perspectives, including s

Strategic Reasoning over Golog Programs in the Nondeterministic Situation Calculus

AAAI 2026technical

We investigate the problem of synthesizing strategies that guarantee the successful execution of a high-level nondeterministic agent program in Golog within a nondeterministic first-order basic action theory, considering the environment as adversarial. Our approach constructs a symbolic program grap

Abstraction of Situation Calculus Concurrent Game Structures

AAAI 2024technical

We present a general framework for abstracting agent behavior in multi-agent synchronous games in the situation calculus, which provides a first-order representation of the state and allows us to model how plays depend on the data and objects involved. We represent such games as action theories of…

Abstraction of Nondeterministic Situation Calculus Action Theories

IJCAI 2023poster

We develop a general framework for abstracting the behavior of an agent that operates in a nondeterministic domain, i.e., where the agent does not control the outcome of the nondeterministic actions, based on the nondeterministic situation calculus and the ConGolog programming language. We assume t…
