Claims

C1strongest claim

We unveil the presence of a cluster composed of delocalized connected solutions. In particular, we demonstrate its stability until a critical threshold κ^{no-mem}_{loc. stab.} (dependent on α).

C2weakest assumption

The local entropy bias is assumed to correctly identify the manifold of connected solutions whose stability governs algorithmic success in the symmetric binary perceptron.

C3one line summary

A new ensemble for connected solutions in CSPs reveals a stable cluster of delocalized solutions in the symmetric binary perceptron up to a critical threshold κ_no-mem_loc.stab. that conventional approaches miss.
