Step Size Comparison: Optimal vs. Conservative

This experiment compares three step size strategies for asynchronous sheaf diffusion on a 4-regular graph with semi-orthogonal restriction maps:

• Synchronous $1/K$: the optimal synchronous step size, applied to the synchronous gradient descent baseline.
• Asynchronous $1/K$: the synchronous-optimal step size applied to the asynchronous algorithm (ignoring delay). Converges in practice for moderate $B$.
• Conservative $0.1/K$: a smaller step that is provably safe even with large delay, at the cost of slower convergence.
