Understanding the problem is the first step to problem-solving. To understand the problem, we need all data to understand the problem.<br \/>\nIt is also important to check whether the problem is solvable. If it is solvable, a complex problem can be broken down into simpler modules, that can be further solved individually.\n<p>This A Level Computer Science module introduces computational methods to your students, explaining:<\/p>\n<ul>\n<li>Problem-solving strategies such as divide and conquer, top-down approach &amp; problem abstraction<\/li>\n<li>Techniques for problem-solving such as back-tracking, data mining, heuristics, pipelining and many more.<\/li>\n<\/ul>\n<p>Computational methods in computer science refer to techniques and approaches used to solve problems or perform tasks using computational tools and algorithms. These methods leverage the power of computers to process and analyze data, simulate systems, and find solutions to complex problems.
