Четверг Introduction to Computational Thinking, Algorithms, and System Logic

Problem Decomposition and Order System Logic

• Computational Thinking:

  • Writing computer programs begins with learning how to think like a computer.
  • Complex, large-scale problems should not be approached as a single unmanageable task; instead, they must be systematically decomposed into smaller, well-defined sub-problems.

• System Inputs and Parameters:

  • System entities include registered members and the specific orders they place.

• Business Rules and Delivery Fee Structure:

  • Minimum Order Threshold: An order amount must reach a minimum threshold of $500\,\text{Turkish lira}$.
  • Standard Surcharge: If an order does not meet the $500\,\text{Turkish lira}$ requirement, a delivery surcharge of $40\,\text{Turkish lira}$ is applied for distances up to $3\,\text{kilometers}$.
  • Alternate Surcharge: A surcharge of $60\,\text{Turkish lira}$ is applied if it is new.

Algorithms and Computer Programs

• Definition of an Algorithm:

  • An algorithm is fundamentally a procedure or a specified step-by-step method designed to solve a given problem.
  • Its primary function is to design and formulate the solution.
  • Example: An order preparation notification procedure constitutes an algorithm.

• Definition and Function of a Program:

  • A program serves as a tool or interface that allows for the practical execution of an algorithm.
  • Its core purpose is the execution of the solution that the algorithm has designed.

• Relationship Between Algorithms and Programs:

  • The algorithm designs the solution; the program executes the solution.

Boolean Logic in Conditional Statements

• Condition Formulation:
  • Program statements rely on logical conditions to direct flow and operational behavior.
  • Logical evaluation rule: When evaluating conditions where both inputs are false, the overall outcome resolves to false ($\text{false} \land \text{false} = \text{false}$).

Course Logistics and Roadmap

• Course Progress:

  • Instruction did not take place during the first week; the current session serves as the inaugural meeting.
  • Initial focus centers on foundational background material, including core terminology and team arrangements.

• Subsequent Milestones:

  • Instruction moves toward tangible programming results and concrete code execution beginning the following week.
  • The inclusion and scheduling of dedicated laboratory sessions remains under review.

Questions & Discussion

• Question / Prompt: What is an algorithm, and what is a program?
  • Audience Response: Participants provided tentative definitions ("Yes, more or less, something like that.").
  • Response / Clarification: An algorithm is the underlying procedure that designs the solution to a problem, whereas a program is the interface and executable tool that carries that procedure out in practice.
