HOFLON: Hybrid Offline Learning and Online Optimization for Process Start-Up and Grade-Transition Controlcs.LG

HOFLON automates process start-ups and grade-changes using offline RL and online optimization.

problem Manual operation of start-ups and grade-changes by experts is declining, leaving plant owners without the necessary tacit know-how.

method HOFLON combines offline RL to learn a latent manifold and long-horizon Q-critic, and online optimization to maximize Q-critic while penalizing deviations and excessive variable changes.

result HOFLON outperforms standard offline RL in industrial case studies, delivering better cumulative rewards than historical data.

Link cobordisms and absolute gradings on link Floer homologymath.GT

We show that the link cobordism maps defined by the author are graded and satisfy a grading change formula. Using the grading change formula, we prove a new bound for $Υ_K(t)$ for knot cobordisms in negative definite 4-manifolds. As another application, we show that the link cobordism maps associated to a connected, cl…

On knots, complements, and 6j-symbolshep-th

The paper connects knot homology, quantum 6j-symbols, and complements of knots.

problem Investigating the relationship between knot homology, quantum 6j-symbols, and knot complements.

method Developed a grading rule for HOMFLY-PT and Kauffman homology, found relationships between A-polynomials, and conjectured closed-form expressions for quantum 6j-symbols and knot complements.

result Closed-form expressions for SO(N) quantum 6j-symbols and conjectured expressions for (a,t)-deformed F_K for knot complements.
