1 introduction to problem solving and programming
The document discusses the steps of problem solving which include identifying the problem, understanding it, identifying alternative solutions, selecting the best solution, listing instructions to implement it, and evaluating the solution. It also describes types of problems that can be solved algorithmically or heuristically and discusses problem solving with computers including defining solutions, results, programs, and artificial intelligence. Finally, it outlines some difficulties in problem solving like eliminating good alternatives or not following logical steps.

Introduces six problem-solving steps: Identify, Understand, Identify alternatives, Select the best, List instructions, Evaluate.
Describes two problem types: Algorithmic (step-based) and Heuristic (trial and error).
Discusses the role of computers in problem solving, including the development of programs and the concept of AI.
Highlights difficulties: Hasty decision making, non-logical sequences, the time required to improve, and the necessity of clarity in instructions.

- 1. Data Structures andAlgorithms Problem Solving Six steps in problem solving @ Identify the problem @ Understand the problem @ Identify alternative ways to solve the problem @ Select the best way to solve the problem from the list of alternative solutions @ List instructions that enable you to solve the problem using the selected solution @ Evaluate the solution Introduction to Problem-Solving and Programming Page 1 of 4
- 2. Data Structures andAlgorithms Types of Problem @ Problems that can be solve with a series of actions. @ Problems that can be solve with knowledge and experience, and a process of trial and error. Algorithmic Solutions a solutions that can be reached in a series of steps Heuristic Solutions a solutions that cannot be reached through a direct set of steps, usually on a trial and error basis Introduction to Problem-Solving and Programming Page 2 of 4
- 3. Data Structures andAlgorithms Problem Solving with Computers Solution @ the instructions listed during step 5 of problem solving - the instructions that must be followed to produce the best results Results @ the outcome of the completed computer-assisted answer Program @ the set of instructions that make up the solution after they have beed coded into a particular computer language Artificial intelligence @ enables a computer to do things like build its own knowledge bank and speak in human language Introduction to Problem-Solving and Programming Page 3 of 4
- 4. Data Structures andAlgorithms Difficulties with Problem Solving a when choosing the best alternative, you might eliminate good alternatives or list the pros and cons too hastily a may not use a logical sequence of steps in your solution a takes practice and time to perfect a one of the most difficult tasks for the problem solver is writing the instructions a assume the computer knows nothing except what you tell it, and think of it as an ignorant but efficient aid to problem solving.
