Storage formats for sparse matrices in Java - Luján, Usman, et al. - 2005 () Citation Context ...re layout is done row-wise. We have used a linear array to store both the Hessian matrix and its induced tensor. However jagged arrays can perform just as well as linear arrays ...

摘要:计算给定布尔公式的模型数量的问题具有许多应用,包括计算定量信息流中的确定性程序的泄漏。模型计数是一个很难的#P完全问题。出于这个原因,在过去十年中已经开发了许多近似计数器,提供了信心和准确性的正式保证。一种流行的方法是基于使用随机XOR约束的概念,粗略地,连续地将解决方案集减半,直到没有模型为止:这通...
the row number of the original matrix. To achieve this diagonals in the lower triangular part of the matrix are padded from the top, and those in the upper triangular part are padded from the bottom. Note that the value ofdistance(i) is the number of elements to be padded for diagonali...
and improve concurrency to allow for parallel treatment. Moreover, these methods detect dense submatrices which can be handled by dense matrix kernels based on multithreaded level-3 BLAS. We will demonstrate for problems arising from circuit simulation, how the improvements in recent years have advanc...
