Prioritized Unit Propagation with Periodic Resetting is (Almost) All You Need for Random SAT Solving [article]

Xujie Si, Yujia Li, Vinod Nair, Felix Gimeno
2019 arXiv   pre-print
We propose prioritized unit propagation with periodic resetting, which is a simple but surprisingly effective algorithm for solving random SAT instances that are meant to be hard.  ...  We share this observation in the hope that it helps the SAT community better understand the hardness of random instances used in competitions and inspire other interesting ideas on SAT solving.  ...  Algorithm 3 summarizes our main SAT solving algorithm, Prioritized Unit Propagation with PEriodic Resetting (PUPPER), which combines prioritized unit propagation and periodic resetting.  ...

Reinforcement Learning [chapter]

Ke-Lin Du, M. N. S. Swamy
2013 Neural Networks and Statistical Learning  
For example, one approach is based on the theory of partially-observable MDPs (POMDPs).  ...  The downside for the Bayesian POMDP approach is its computational expense and its strong reliance on complete environment models.  ...  The space of all possible tasks is thus a unit square, as shown in Figure 2 .2.  ...

Visible Light-Assisted Soft-Chemistry Route to Silver Nanomaterials at Room Temperature

Yi Wu, Xin Liu, Zi Huang, Xiang Fei He, Xi Yang, Qing Li
2019 Key Engineering Materials  
AgNPs were characterized with powder X-ray diffraction (XRD) and scanning electron microscope (SEM). The result showed that the nanoparticles are spherical and cube.  ...  Silver nanoparticles (AgNPs) were synthesizd by a light-assisted liquid phase reduction method with sodium hypophosphite as a reducing agent. DTAB was used to perform as the surfactant.  ...  I encourage you to enjoy all opportunities the organizers have prepared for you and more.  ...

2015 Insight  
The problem is when you have hundreds of monitors and related actions you never know what will happen if things interfere, etc. A persistent question is: "How do you validate it?"  ...  Erv Baumann uses the term collective redundancy to describe the idea that if you have multiple copies of physically separate units (e.g., a number of formation-flying UAVs or CubeSats), you can leverage  ...  CASPER is designed for embedded online applications whereas ASPEN is designed for offline use. c.  ...

2017 Zenodo  
Indeed, it's our aim in this book to provide you with a modern introduction to the dynamic field of computer networking, giving you the principles and practical insights you'll need to understand not only  ...  And if so, is it possible that it actually could be both interesting and fun to learn about computer networks? Fortunately, the answer to all of these questions is a resounding YES!  ...  Propagation Delay Once a bit is pushed into the link, it needs to propagate to router B. The time required to propagate from the beginning of the link to router B is the propagation delay.  ...

Using complexity to protect elections

Piotr Faliszewski, Edith Hemaspaandra, Lane A. Hemaspaandra
2010 Communications of the ACM  
So you might argue that you don't need to know how many copies you need to keep your data safe for the long term, you just need to know how many you need to keep it safe for the next few years.  ...  Today's SAT solvers, which enjoy wide industrial usage, routinely solve SAT instances with over one million variables. How can a scary NP-complete problem be so easy? What is going on?  ...  So, the last thing you probably have on your mind is whether or not you are properly insured.  ...
