W artykule przedstawiono aktualny stan wiedzy nt. geologii utworów solnych cechsztynu i miocenu w Polsce, opierając się na najważniejszych opublikowanych wynikach badań prowadzonych od początku XXI w. Autorzy przeglądowo omawiają osiągnięcia w różnych dziedzinach – stratygrafii, sedymentologii, geochemii, mineralogii, tektoniki, hydrogeologii i badań geofizycznych utworów solnych oraz przedstawiają obecny stan udokumentowanych i szacunkowych zasobów soli w Polsce. Analizują także różne formy zagospodarowania wystąpień soli (produkcja soli kruszonej i solanki, magazyny mediów i składowiska odpadów) oraz posteksploatacyjnego funkcjonowania kopalń, wskazują istotne ich zdaniem kierunki, w których winny być prowadzone dalsze badania.

This article provides an overview on the current state of knowledge on salt geology in Poland. Salt occurs in Poland in two salt- bearing formations: Zechstein (Permian) and Miocene (Neogene). The review briefly presents information on the various aspects of salt mining as well as description of results of different research topics discussed by scientists since the beginning of the 21st century: stratigraphy, sedimentology, geochemistry, mineralogy, geophysics, tectonics, hydrogeology as well as reserves and resources of salt deposits. Various forms of management of salt occurrences (crushed salt and brine production, storages of media, and waste disposals) and the post-mining activity of salt mines are commented. This review is based on extensive literature and proposes main directions of future studies in salt geology of Poland.

Differential Evolution (DE) is a popular and efficient continuous optimization technique based on the principles of Darwinian evolution. Asynchronous Differential Evolution is a DE generalization that allows to regulate the synchronization mechanism of the algorithm by tuning two additional parameters. This paper, after providing a further experimental analysis of the impact of the DE synchronization scheme on the evolution, introduces three self-adaptive techniques to handle the synchronization parameters. Moreover the integration of these new regulatory synchronization techniques into state-of-the-art (self) adaptive DE schemes are also proposed. Experiments on widely accepted benchmark problems show that the new schemes are able to improve performances of the state-of-theart (self) adaptive DEs by introducing the new synchronization parameters in the online automated tuning process.

One of the most relevant problems related to most of the objective full-reference image and video quality assessment methods is their correlation with subjective perception of various types of distortions. Since the relation between the subjective scores, typically expressed as Mean Opinion Scores (MOS) or Differential MOS, and most of the metrics is nonlinear, various mapping functions are used in order to linearize this relation e.g. logistic function recommended by the Video Quality Experts Group (VQEG). Such compensation can also be conducted using some other function e.g. polynomial or exponential ones. Nevertheless, the results obtained for each of available datasets differ and such approach cannot be considered as universal. One of possible solutions, proposed in some earlier papers, is the use of combined metrics, which have significantly higher linear correlation with MOS or DMOS values without the necessity of nonlinear mapping. The comparative analysis of the optimisation results for some “state-of-the-art” metrics and proposed combined ones is also provided in the paper.
