HyEvo: Self-Evolving Hybrid Agentic Workflows
HyEvo is an automated workflow-generation framework that combines probabilistic LLM nodes for semantic reasoning with deterministic code nodes for efficient execution. It employs an LLM-driven multi-island evolutionary strategy with reflect-then-generate to optimize hybrid workflows via execution feedback. Experiments demonstrate superior performance on reasoning and coding benchmarks, with up to 19x inference cost and 16x latency reductions over SOTA baselines.
