ASCT: Attentive Search over Counterfactual Trees for Credit Assignment in Agentic Reinforcement Learning
Yang Li, Jinhan Yang, hai liu +8
Terminal utility evaluates a complete agentic workflow, but learning requires credit for the decisions within it. We introduce Attentive Search over Counterfactual Trees (ASCT), a…
From Evidence to Effect: Authority Semantics and Runtime Infrastructure for Stateful Agents
Yang Li, Sergey Volkov, Hai Liu +9
Stateful agents reuse artifacts after producing executions and permissions change. We formalize authority-sufficient observations and durable effects bound to execution and materia…
Agent-UCT: Upper Confidence Bounds Applied to Trees for Cost-Aware Agentic Workflow Optimization
Yang Li, Hai Liu, Dian Shao +9
Workflow search pays for complete quality observations, whose execution cost changes as reusable prefixes accumulate. AgentUCT uses an economic model of the remaining evaluation co…
StateFuse: Deterministic Conflict-Preserving Memory for Multi-Agent Systems
Sergey Volkov, Yang Li, Ye Luo
Agent systems accumulate conflicting observations across branches, retries, and replicas, yet many practical memory layers still collapse disagreement behind overwrite rules that a…
