Thrifty Zero-Knowledge - When Linear Programming Meets Cryptography [article]

Simon Cogliani, Houda Ferradi, Rémi Géraud, David Naccache
2016 IACR Cryptology ePrint Archive  
These protocols are constructed by introducing a bias in the challenge send by the prover. This bias is chosen so as to maximize the security versus effort trade-off.  ...  We illustrate the benefits of this approach on several well-known zero-knowledge protocols.  ...  .: Using optimization to break the epsilon barrier: A faster and simpler width-independent algorithm for solving positive linear programs in parallel.  ...

Contact and friction simulation for computer graphics

Sheldon Andrews, Kenny Erleben, Zachary Ferguson
2022 ACM SIGGRAPH 2022 Courses  
Programming examples are provided in our appendix as well as on the course website to accompany the course notes.  ...  We briefly cover several approaches for contact generation using discrete collision detection. Then, we present a range of numerical techniques for solving the associated LCPs and NCPs.  ...  A critical part of the IPC algorithm is ensuring the optimization does not take a step that jumps over the barrier. To accomplish this CCD is added to the line-search within the optimization.  ...

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  
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.  ...  The ultraviolet-visible (UV-vis) absorption and the fluorescent properties of the as-prepared AgNPs were explored.  ...  The paper addresses unresolved issues with regard to the problem of partitioning the criterion cone of a multiple objective linear program (MOLP) into sub-cones for the purpose of solving an MOLP in parallel  ...
