Algorithmic Thinking: The Key for Understanding Computer Science Gerald Futschek Vienna University of Technology Institute of Software Technology and Interactive Systems Favoritenstrasse 9‚ 1040 Vienna‚ Austria futschek@ifs.tuwien.ac.at Abstract. We show that algorithmic thinking is a key ability in informatics that can be developed independently from learning programming. For this purpose we use problems that are not easy to solve but have an easily understandable problem definition. A proper

● Iterative Deepening Depth-First Search ● A* algorithm Iterative Deepening A-star (IDA*) CSC 171 – Introduction to AI 2 Description Iterative Deepening A* is a graph traversal and path search algorithm that can find the shortest path between a designated start node and any member of a set of goal nodes in a weighted graph. It is a variant of iterative deepening search that borrows the idea to use a heuristic function to evaluate the remaining cost to get to the goal from the A* search algorithm

Canada is a developed country‚ with advances in public sanitation‚ medicine‚ and public health. All of which give Canada a low mortality rate. Immigration also plays a big part in Canada’s population growth‚ as Canada is considered by many to

experiencing the most difficulties as the surrounding glaciers are all melting. Our primary focus is on polar bears as they rely on masses of ice to rest after hunting for food. With the emergence of warmer climate‚ the areas of ice are diminishing leaving polar bears swimming for even longer until they drown from exhaustion. A federal regulation was passed in May of 2008 to protect the polar bear species from extinction by adding them to the endangered list. This should be a wake-up call to every

Evolution of Polar Bears The observed fossil transitions that inform our knowledge of Polar Bear speciation are very well documented. Bear fossils change through time: generally‚ when examining the fossil record‚ successively deeper levels of sediments or sedimentary rocks yield successively older fossils. For some transitions from one species to another‚ one can find a well-characterized series of transitional specimens leading the observer across the species "boundaries" (Kurten‚ 1976). Sometime
