Large Neighborhood Prioritized Search for Combinatorial Optimization with Answer Set Programming

Kavli Affiliate: Naoyuki Tamura | First 5 Authors: Irumi Sugimori, Katsumi Inoue, Hidetomo Nabeshima, Torsten Schaub, Takehide Soh | Summary: We propose Large Neighborhood Prioritized Search (LNPS) for solving combinatorial optimization problems in Answer Set Programming (ASP). LNPS is a metaheuristic that starts with an initial solution and then iteratively tries to find better solutions […]

Supermassive black hole formation from Affleck-Dine mechanism with suppressed clustering on large scales

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Kentaro Kasai, Masahiro Kawasaki, Kai Murai, Shunsuke Neda, | Summary: We study a primordial black hole (PBH) formation model based on the framework of the inhomogeneous Affleck-Dine (AD) mechanism, which can explain the seeds of supermassive black holes (SMBHs). This model, however, predicts strong clustering of SMBHs […]

Cosmological Consequences of Unconstrained Gravity and Electromagnetism

Kavli Affiliate: Tom Melia | First 5 Authors: Loris Del Grosso, David E Kaplan, Tom Melia, Vivian Poulin, Surjeet Rajendran | Summary: Motivated by the quantum description of gauge theories, we study the cosmological effects of relaxing the Hamiltonian and momentum constraints in general relativity and Gauss’ law in electromagnetism. We show that the unconstrained […]

Extracting parity-violating gravitational waves from projected tidal force tensor in three dimensions

Kavli Affiliate: Misao Sasaki | First 5 Authors: Teppei Okumura, Misao Sasaki, , , | Summary: Gravitational waves (GWs) may be produced by various mechanisms in the early universe. In particular, if parity is violated, it may lead to the production of parity-violating GWs. In this paper, we focus on GWs on the scale of […]
