Loop

What is Loop Node?

A Loop node executes repetitive tasks that depend on previous iteration results until exit conditions are met or the maximum loop count is reached.

Loop vs. Iteration

Type	Dependencies	Use Cases
Loop	Each iteration depends on previous results	Recursive operations, optimization problems
Iteration	Iterations execute independently	Batch processing, parallel data handling

Configuration

Parameter	Description	Example
Loop Termination Condition	Expression that determines when to exit the loop	x < 50, error_rate < 0.01
Maximum Loop Count	Upper limit on iterations to prevent infinite loops	10, 100, 1000

Configuration

Usage Example

Goal: Generate random numbers (1-100) until a value below 50 appears.

Steps:

1. Use node to generate a random number between 1-100.

2. Use if to evaluate the number:

   • If < 50: Output done and terminate loop.

   • If ≥ 50: Continue loop and generate another random number.

3. Set the exit criterion to random_number < 50.

4. Loop ends when a number below 50 appears.

Steps

Planned Enhancements

Future releases will include:

- Loop variables: Store and reference values across iterations for improved state management and conditional logic.

- `break` node: Terminate loops from within the execution path, enabling more sophisticated control flow patterns.
