Default Initial Condition 편집하기

'''Default Initial Condition''' refers to the predefined starting values or states used in algorithms, mathematical models, and computational systems. These conditions serve as the foundation for computations and ensure consistent behavior across executions.
==Key Concepts==
*'''Initial Condition:''' The starting state or value assigned to variables before an algorithm or system begins execution.
*'''Default Values:''' Predefined values used when no user-defined input is provided.
*'''Recursion and Sequences:''' Base cases in recursive functions and mathematical sequences often rely on default initial conditions.
==Examples==
===Recursive Algorithms===
In recursion, base cases define default initial conditions:
*'''Factorial Function'''
**f(0) = 1 (Base case)
**f(n) = n × f(n-1) for n > 0.
*'''Fibonacci Sequence'''
**F(0) = 0, F(1) = 1 (Default conditions)
**F(n) = F(n-1) + F(n-2) for n ≥ 2.
===Data Structures===
*'''Arrays'''
**Default values: 0 (numeric types), false (boolean), null (object references).
*'''Linked Lists'''
**Head pointer is initialized as null if the list is empty.
*'''Stacks and Queues'''
**The default condition is an empty structure before elements are pushed or enqueued.
===Differential Equations===
*In mathematical modeling, initial conditions specify starting values:
**Example: y(0) = 5 in a differential equation dy/dx = 3x².
===Programming Defaults===
*'''Default Function Parameters'''
**Python: def func(x=10) → x defaults to 10 if no value is passed.
*'''Database Defaults'''
**SQL: DEFAULT constraint assigns values if no explicit value is provided.
==Importance==
*Ensures predictable and consistent behavior in algorithms.
*Provides a well-defined starting state for recursive functions and simulations.
*Helps avoid undefined behavior in programming and mathematical computations.
