COMP 1701 Algorithms: Problem Solving and Pseudocode

Study Notes

Algorithm Challenges and Components

The main challenge in devising an algorithm is ensuring it efficiently solves the problem while managing complexity.
Key components of an algorithm include inputs, outputs, and the steps needed to transform inputs into outputs.

Pseudocode and Algorithm Techniques

Pseudocode serves as a simplified representation of an algorithm, making it easier to understand and communicate ideas before actual coding.
'Hill Climbing' is a search algorithm used for optimization problems, focusing on improving a solution iteratively by moving towards better solutions.

User Interaction in Algorithms

After a user enters a number, the key action taken is typically to process that number as part of the algorithm’s defined operations.
When a user provides multiple numbers followed by nothing, the algorithm typically evaluates the provided numbers and may terminate further input processing.

Design Phase in Problem-Solving

Steps in the Design Phase of problem-solving may include defining requirements, breaking down the problem, and creating algorithms or solutions.
The main takeaway emphasizes the importance of structured approaches to problem-solving, including iterative refinement and evaluation.

Fundamental Concepts of Algorithms

An algorithm in computing is defined as a sequence of instructions designed to perform a specific task or solve a particular problem.
Two main components required for problem-solving include understanding the problem itself and developing a feasible solution.

Phases of Problem-Solving

The phase that involves writing code and testing is known as the Implementation Phase, where the designed solutions are translated into executable programs.
The first step in problem-solving typically involves identifying and analyzing the problem to establish a clear understanding of the needs to be addressed.
