( e.g. sorting books by alphabetical order ). Keyang. He. Discrete Mathematics. Basic Concepts. Algorithm . – . a . specific set of instructions for carrying out a procedure or solving a problem, usually with the requirement that the procedure terminate at some point. Insertion Sort. Insertion Sort. Start with empty left hand, cards in pile on table.. Take first card from pile, put in left hand.. Take next card from pile, insert in proper place among cards in left hand.. 1987. 1964. 1997. 1974. Sorting . Algorithms. Algorithm. . Sort these 6 socks. How to determine which comes first?. Compare 2 at a time. Draw arrows . from. . an “earlier” sock . to. . a “later” one.. As many arrows as you wish to show the sorting order you have decided.. Onset of . precip. – development of particles large enough to sediment relative to cloud droplets & ice crystals.. Larger particles tend to fall faster.. Differential Sedimentation (D.S.). Atmospheric flows (e.g. updrafts) can prolong D.S. due to the removal of small drops upward & exhausted through the anvil region.. Chapter 14. Selection. . Sort.

Realism was not their goal but to communicate religious ideas. At first, borrowed from the Romans but began to go their own direction. Earliest surviving Christian art is found on frescoed walls of the catacombs of Rome.. Problem - a well defined task.. Sort a list of numbers.. Find a particular item in a list.. Find a winning chess move.. Algorithms. A series of precise steps, known to stop eventually, that solve a problem.. In this lesson, we will:. Describe sorting algorithms. Given an overview of existing algorithms. Describe the sorting algorithms we will learn. Sorting. Given an array that has arbitrary entries, . int array[10]{82, 25, 32, 85, 16, 36, 40, 4, 28, . 10 Bat Algorithms Xin-She Yang, Nature-Inspired Optimization Algorithms, Elsevier, 2014 The bat algorithm (BA) is a bio-inspired algorithm developed by Xin-She Yang in 2010. 10.1 Echolocation of Bats Comparison Sorts.
