Algorithm 20.1 shows the main procedures of the ABT algorithm. Its presentation is slightly adapted so that it can also be used for optimization, following ([31]) and ([34]). It uses the construct call to indicate that the agent sends a message to another agent, thus invoking the receivin...

Recently, I remembered that when I was a student, I read about Huffman coding which is a clever compressing algorithm and ever since wanted to implement it but did not found a chance. Last week – I finally did it. To test my implementation – I took a 160 KB file containing the text...
If PolyBase encounters an unexpected error during the distributed query optimization phase, and tries to create a memory dump to capture the state of the system, you may notice that the dump creation fails. In ...
FIX: PolyBase may fail to generate dumps if an error occurs during the distributed query optimization phase in SQL Server 2019
designing a novel distributed projection-free and gradient-free algorithm for dso problems. we provide rigorous theoretical analysis on the convergence rate and complexity guarantee of the proposed algorithm, which enjoys a convergence rate comparable to centralized stochastic first-order optimization ...
