THE FIRST MAINLAND EUROPEAN MESOZOIC CLICK-BEETLE (COLEOPTERA: ELATERIDAE) REVEALED BY X-RAY MICRO-COMPUTED TOMOGRAPHY SCANNING OF AN UPPER CRETACEOUS AMBER FROM HUNGARY

Abstract Fossil bioinclusions in amber are invaluable source of information on the past evolution and diversity of various organisms, as well as on the paleoecosystems in general.The click-beetles, Elateridae, which originated and greatly diversified during the Mesozoic, are mostly known from the adpression-like fossils, and their diversity in the

In this paper, we propose a hybrid ACO algorithm for solving vehicle routing problem (VRP) heuristically in combination with an exact In the basic VRP, geographically scattered customers of known demand are supplied from a single depot by a fleet of identically capacitated vehicles.The intuition of the proposed algorithm is that nodes which are nea
