We refute the Probabilistic Universal Graph Conjecture of Harms, Wild, and Zamaraev, which states that a hereditary graph property admits constant-size probabilistic universal if only it is stable has at most factorial speed. Our counter-example follows from existence sequence n×n Boolean matrices Mn, such their public-coin randomized communication complexity tends to infinity, while every subm...

The mirin contribution of this report is the development of novel algorithms {that make efficient use of the communication system in distributed memory architectures with plrocessing elements interconnected by a hypercube network. These algorithms achieve almost optirr~al overlap of communicatior~ delays by computation, leading to a minimization of communicatioi~ overhead. Rigorous ana1yt:ical ...

the study focused on the analysis of production and marketing constraints of tomato among rural farmers in talensi nabdam district of upper east region of ghana.a total of 100 respondents were interviewed using questionnaire. data was analyzed using descriptive statistics to describe the socio economic characteristics of the farmers and kendall’s coefficient of concordance was used to rank the ...

This paper studies a classic maximum entropy sampling problem (MESP), which aims to select the most informative principal submatrix of prespecified size from covariance matrix. MESP is widely applied many areas, including healthcare, power systems, manufacturing, and data science. By investigating its Lagrangian dual primal characterization, we derive novel convex integer program for show that ...
