Finally, the relationship between algorithm and performance, to measure the quality of an algorithm, mainly evaluates time and space by the amount of data, which will directly affect the program performance in the end. Generally, the space utilization rate is small, and the time required is rela...
To a great extent, IT complexity is also the result of an uncontrolled proliferation of redundant IT systems, caused by the IT organization's tendency to follow a stovepipe system integration style. In an enterprise with silo-based organizational partitions, each business unit typically has its own...
We assume three degenerate O2p orbitals as used before29 for demonstration of the approach, while later extend it to multiorbital models. To attain converged posterior distributions, 200k MCMC sampling steps with the Metropolis–Hastings algorithm were performed in a multidimensional parameter space ...
By properly choosing algorithm parameters, we show, for objective function value gap and constraint violation, the worst-case \\(\\mathcal {O}\\left( {1}/{\\sqrt{k}}ight) \\) and \\(\\mathcal {O}\\left( {\\ln k}/{k}ight) \\) convergence rates in expectation measured by ...
A trust management mechanism for mobile ad hoc networks (MANETs) is proposed to cope with security issues that MANETs face due to time constraints as well as resource constraints in bandwidth, computational power, battery life, and unique wireless charac
of the sequence. For instance, C1 comprises seismicity in the northern part of the subhorizontal detachment, parts of the normal fault (Mt. Vettore) that ruptured during the Norcia mainshock, and this mainshock hypocenter itself. C2 represents seismicity in the southern part of the sub...
e., problems having an algorithm with running-time \mathcal {O}(g(k) \cdot f(n)), for a computable function g and polynomial f. In order to argue about fixed-parameter intractability, we need the following kind of reductions. A (classical) many-one reduction R from a parameterised ...
This model incorporates all the information that can be extracted from the data with the given class of models, and its code length is defined to be the information in the data. The second part in the complexity represents the code length for noninformative noise. Such a decomposition provides...
Additionally, we ran the clustering algorithm multiple times to ensure the stability of the obtained structure. The results of different runs are almost the same. We observed only two possible clustering configurations, occurring roughly with the same frequency. The first configuration corresponds to ...
the matrixWrepresents a weighted incidence matrix of an undirected bipartite network uniquely describing the relations between countries and products – this would no longer be true if two different matrices were used for the transformation; moreover, the feature of symmetry for the matricesNandGis es...
