Despite its NP-completeness, the Boolean satisfiability problem gave birth to highly efficient tools that are able to find solutions to a Boolean formula and compute their number. Boolean formulae compactly encode huge, constrained search spaces for variability-intensive systems, e.g., the possible configurations of the Linux kernel. these search spaces are generally too big to explore exhaustively, leading most testing approaches to sample a few solutions before analysing them. A desirable property of such samples is uniformity: each solution should get the same selection probability. this property motivated the design of uniform random samplers, relying on SAT solvers and counters and achieving different tradeoffs between uniformity and scalability. though we can observe their performance in practice, understanding the complexity these tools face and accurately predicting it is an under-explored problem. Indeed, structural metrics such as the number of variables and clauses involved in a formula poorly predict the sampling complexity. More elaborated ones, such as minimal independent support (MIS), are intractable to compute on large formulae. We provide an efficient parallel algorithm to compute a related metric, the number of equivalence classes, and demonstrate that this metric is highly correlated to time and memory usage of uniform random sampling and model counting tools. We explore the role of formula preprocessing on various metrics and show its positive influence on correlations. Relying on these correlations, we train an efficient classifier (F1-score 0.97) to predict whether uniformly sampling a given formula will exceed a specified budget. Our results allow us to characterise the similarities and differences between (uniform) sampling, solving and counting.

the article is devoted to the results of the adaptive filtering synthesis in the frames of neuromorphic model inspired by biological sensory system. To adequately model the perception mechanisms the analysis and synthesis are carried out on the base of the most realistic representation of input data-external stimuli-in the form of the stream of receptor registration events. Statistical model of that stream is chosen in the form of Poisson two-dimensional point processes. On this basis, a statistical description of the input data in the form of a sampling representation is proposed. the model of neural encoding of input data is considered in the article within the framework of the receptive fields concept. A number of well-known neuro-mechanisms are implemented in the encoding model, including in particular, center/surround inhibition. Decoding issues are considered in the context of stimuli spatial contrasts restoration, which partially models the responses of so-called simple cells in the visual cortex. It is shown that the model of coupled ON-OFF-decoding admits the sharp image details restoring in the form of local edges. At the end of the article, to justify the adequacy of the synthesized encoding procedure-adaptive filtering-we demonstrate an example of image edge directed interpolation and discus the results in the terms of perceptual quality.
