This week in my Exploring Computer Science class we learned all about Algorithms. A Algorithm is a set a set of step by step rules or problem solving structure especially for computer or a electronic device  to follow by. Computers are dumb machines that we literally have to tell them what to do. Four steps to problem solving is 1. To Understand the problem 2. Plan your solution 3. Test your plan to solve the problem 4. Review. Some people that may have to create and use algorithms are... Computer programmers, and software developers. MST(Minimal Spanning Tree) which is a algorithm used to find the shortest path.
