Study Notes
Introduction to Computer Science
- Computer science focuses on computational problem-solving through computation.
- Key areas include software engineering, database management, computer networks, data mining, information security, programming language design, computer architecture, human-computer interaction, robotics, and artificial intelligence.
- An algorithm is defined as a systematic series of steps to solve a specific type of problem.
Computational Problem Solving
- Two essential components:
- Representation: Captures relevant problem aspects.
- Algorithm: Utilizes the representation to solve the problem.
- Example problem: A man must transport a cabbage, goat, and wolf across a river without leaving the goat and wolf alone with the cabbage or goat.
Man, Cabbage, Goat, Wolf Problem Solution
- A brute force approach tests all possible combinations of which item to row back.
- Relevant information includes the location of each item at each step, while irrelevant details are omitted.
Limits of Computational Problem Solving
- After developing an algorithm, a crucial consideration is whether solutions can be found in a reasonable time frame.
- Example: The Traveling Salesman problem involves finding the shortest route to visit a set of cities.
- A brute-force method calculates all possible routes (e.g., 10 cities = 10! possible routes).
- With 20 cities, computing all routes would take over 77,000 years at one million computations per second, highlighting impracticality.
Understanding Algorithms
- An algorithm is a finite sequence of clearly defined and feasible steps leading to a desired result for given input, ultimately terminating in a finite time.
- Algorithms are fundamental to computer science, providing systematic computation methods.
- Example algorithm: Determine if a number ( N ) is even or odd by checking the remainder of ( N ) divided by 2.
