GRPO-GCC: Enhancing Cooperation in Spatial Public Goods Games via Group Relative Policy Optimization with Global Cooperation Constraint
Inspired by the principle of self-regulating cooperation in collective institutions, we propose the Group Relative Policy Optimization with Global Cooperation Constraint (GRPO-GCC) framework. This work is the first to introduce GRPO into spatial public goods games, establishing a new deep reinforcement learning baseline for structured populations. GRPO-GCC integrates group relative policy optimization with a global cooperation constraint that strengthens incentives at intermediate cooperation l…

Cobordism maps in Khovanov homology and singular instanton homology II
This paper is a continuation of our previous work, where we defined an embedded cobordism map on the instanton cube complex that recovers the cobordism maps both in Khovanov homology and singular instanton theory. In this paper, we extend this construction to immersed cobordisms. As an application, we show that, for any smooth, oriented (not necessarily ribbon) concordance $C$ from a two-bridge torus knot, the induced map $\widetilde{Kh}(C)$ on reduced Khovanov homology is injective, with the l…

Welcome back - been busy the last days with meeting friends etc 🙂
But I wanted to show some more #photos from the #Lotharsteig in the #nationalparkschwarzwald . Different from …

A serene scene of a wooden path winding its way through a lush forest is captured in this image. The path is surrounded by tall trees with green leaves, creating a canopy overhead. The forest floor is covered with grass and various types of vegetation. In the background, the forest continues on, creating a peaceful and natural landscape. The image evokes a sense of tranquility and connection to nature.
A close-up photo of a sign mounted on a tree stump in a natural outdoor setting. The image shows a wooden path cutting through tall grass, leading up to the tree stump. The tree stump is surrounded by lush greenery, with a tree in the background with green leaves. The sign appears weathered and worn, possibly indicating directions or information for visitors. The color palette of the scene is predominantly grey, with accents of blue in the sky. The overall atmosphere suggests a peaceful nature …

ConPoSe: LLM-Guided Contact Point Selection for Scalable Cooperative Object Pushing
Object transportation in cluttered environments is a fundamental task in various domains, including domestic service and warehouse logistics. In cooperative object transport, multiple robots must coordinate to move objects that are too large for a single robot. One transport strategy is pushing, which only requires simple robots. However, careful selection of robot-object contact points is necessary to push the object along a preplanned path. Although this selection can be solved analytically, …
