Visual TL;DRQuickExplainDeeper

The brittleness of static memory in LLM agents operating in dynamic environments is a critical bottleneck. Existing agents treat memory as a fixed repository, failing to adapt to continuous feedback, task variations, and heterogeneous signals that reshape what and how information should be connected.

Evolving Memory Topology for Agentic Robustness

The proposed FluxMem memory framework addresses this by modeling memory as a heterogeneous graph that dynamically refines its topology. This evolution occurs across three stages: initial connection formation, feedback-driven refinement, and long-term consolidation. During execution, FluxMem actively repairs broken links, prunes irrelevant interference, aligns abstraction granularities, and distills successful trajectories into reusable procedural circuits. This is guided by a novel metric for memory generalizability and evolutionary maturity.

State-of-the-Art Adaptation in Complex Environments

The FluxMem memory framework demonstrates significant advancements, achieving consistent state-of-the-art performance across three fundamentally distinct benchmarks: LoCoMo, Mind2Web, and GAIA. This consistent success highlights its strong adaptation and generalization capabilities in complex agentic environments, moving beyond static memory limitations.
