- Learning about algorithms helps develop more efficient solutions, saving time and resources in various applications.
- Algorithms are applicable in various disciplines such as mathematics, engineering, and natural sciences.
Algorithm Definition
- An algorithm is a sequence of steps to accomplish a particular task.
- A good algorithm should use resources like CPU time and memory judiciously.
- The output produced by an algorithm lies in a set called range, and the input is taken from a set called domain.
Characteristics of an Algorithm
- An algorithm can have zero or more inputs.
- An algorithm must have at least one output.
- An algorithm should be efficient in terms of memory and time.
- An algorithm should be finite.
- Every statement in an algorithm should be unambiguous.
Ways of Writing an Algorithm
- English-like Algorithm: can be written in simple English, but lacks the characteristic of being definite.
- Flowcharts: graphical representations of processes or workflows, consisting of symbols and connectors that depict the sequence of steps, decisions, and actions involved in a process.
Importance of Algorithms in Real-World Applications
- Google's Search Engine uses the PageRank (PR) algorithm to order search results.
- Google Maps uses the shortest path algorithm to provide driving directions.
- Algorithms are important in biological endeavors, such as searching and sorting algorithms used to extract information from billions of DNAs.
This course introduces the design and analysis of algorithms, teaching students to think algorithmically and familiarize themselves with core algorithms and design techniques.
