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…

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, …

Weekend #Plankton Factoid 🦠🦐
The White Cliffs of Dover are an iconic formation often seen on television or films that can be over 100 m high. The white colour is chalk "biomicrite" formed by the compacted deposits from dense blooms of Coccolithophore phytoplankton covered with distinct plates of calcite (coccoliths) in a shallow sea during the Late Cretaceous. The dark bands of fli…

Just disposing of a couple Indian pickles in my substantial collection. These two had a pretty good run. Need to make room in the cupboard for more recent acquisitions.

Back to the HMCAD1520 FA.
This is sample 6A1 after initial partial decap. It's still covered in the north and easy because I guessed how big the die would be and apparently underestimated its size.
The good news is that it's gold ball bonded, so more time in the acid shouldn't risk damaging the bond wires at all.
Time to re-mount it with a bigger mask and try again.
