Study Notes

Algorithm Design and Analysis

  • Algorithms are precise sequences of instructions for solving problems.
  • Problem-solving steps include: problem definition, algorithm design, algorithm analysis, implementation, and evaluation.
  • Defining a problem involves identifying the problem type, constraints, inputs and outputs.
  • Algorithm characteristics include inputs, outputs, accuracy, correctness, efficiency, and generality.

Algorithm Properties

  • Algorithms must have clearly defined inputs.
  • They need to produce clear outputs.
  • Instructions must be precise and unambiguous.
  • Algorithms should complete tasks in reasonable time.
  • Algorithms should be applicable to various inputs.

Steps to Solve a Problem Systematically

  • First, define the problem, meaning determining the problem type, constraints, inputs and outputs.
  • Then analyze the problem, finding starting and ending points and needed data.
  • Next, formulate, using mathematical or formal descriptions.
  • Algorithm design, planning the solution.
  • Analyze the algorithm, estimating its time and space complexity.
  • Implement, running the algorithm.
  • Finally, evaluate the solution by inspecting the results and assessing efficiency.

Representing Algorithms

  • Natural language (everyday language) is often used to describe algorithms, but may not be universally understood.
  • Specific programming languages (like C++, Java, or Pascal) can also represent algorithms. However, this can be less accessible.
  • Pseudocode provides a middle ground, combining natural language and programming language features for a structured outline of an algorithm.
