Improving the Parallelized Pollard Lambda Search on Binary Anomalous Curves

The best algorithm known for finding logarithms on an elliptic curve (E) is the (parallelized) Pollard lambda collision search. We show how to apply a Pollard lambda search on a set of equivalence classes derived from E, which requires fewer iterations than the standard approach. In the case of binary anomalous curves over F2m , the algorithm speeds up the standard algorithm by a factor of p2m.

We show how to apply a Pollard lambda search on a set of equivalence classes derived from E, which requires fewer iterations than the standard approach.

Armentum: a hybrid direct search optimization methodology

Design of experiments (DOE) offers a great deal of benefits to any manufacturing organization, such as characterization of variables and sets the path for the optimization of the levels of these variables (settings) trough the Response surface methodology, leading to process capability improvement, efficiency increase, cost reduction. Unfortunately, the use of these methodologies is very limite...

Direct Binary Search with Adaptive Search and Swap

Grayscale halftoning is the technique of approximating a grayscale image by a black-and-white image. Black-and-white printers use halftoning to replicate grayscale images on paper. The printers have only the black of ink and the white of paper as the colors at their disposal. Although the printers may vary the size of dots they drop, they cannot vary the intensity of the droplets. All droplets ...
