Abstract Background Protein sequences are subject to a mosaic of constraint.Changes to functional domains and buried residues, for example, are more apt to disrupt protein structure and function than are changes to residues participating in loops or exposed to solvent.Regions of constraint on the tertiary structure of a protein often result in loos
Task of lossy image compression based on discrete cosine transform (DCT) is considered.For image blocks having size 8x8 pixels chorulon hcg (it corresponds to division of images on blocks in JPEG standard) presence of correlation between different DCT coefficients of the same block as well as between coefficients of different blocks is analyzed.Val
CVRP (Capacitated Vehicle Routing Problems) is the integrated optimization of VRP and Bin Packing Problem (BPP), which has far-reaching practical significance, because only by taking both loading and routing into consideration can we make sure the delivery route is the most economic and the items are completely and reasonably loaded into the vehicl
