Objectives Data Structures Algorithms

Data structure Data structure – method to store information

Algorithms Algorithm – method for solving a problem Algorithm – a process or set of rules to be followed in calculations or other problem-solving operations

Algorithms Algorithms are at the heart of computing. Any system, be it software or hardware, will have algorithms (and data structures) as its basic building blocks. Schneider F.B. Rodd M (Eds) ‘International Review of UK Research in Computer Science’, (2001) http://www.iee.org/policy/csreport/cs_report.pdf

Why study Algorithms? If you know about available algorithms you can: avoid re-inventing the wheel. select best algorithm based on information on complexity for different tasks. develop new algorithms more easily.
