FIND OPTIMUM VALUE FROM THE CURVE¶
Applies a hill-climbing search algorithm to a curve to find its optimal (minimum or maximum) Y value within a specified X range. Use this worker when you need to locate an extremum on a noisy or complex curve without requiring gradient information.
When to use¶
Classification: process.
Tagged: curve, extremum, hill_climbing, maximum, minimum, optimization, search.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve | curve | vector | — | Input curve (X/Y vector) on which the hill-climbing search is performed; must be provided as a d3VIEW curve object. | |
| Curve | objective | list | minimize | Optimization direction: choose ‘minimize’ to find the lowest Y value or ‘maximize’ to find the highest; defaults to ‘minimize’. | |
| Min Time Window | start_x | scalar | 0.0 | Left boundary of the X search window; set to 0.0 to start from the beginning of the curve (same units as the curve’s X axis). | |
| Max Time Window | end_x | scalar | 0.0 | Right boundary of the X search window; set to 0.0 to search through the end of the curve (same units as the curve’s X axis). | |
| Step Size For X | step_sizefor_x | scalar | 0.0001 | Increment by which X is advanced at each hill-climbing step; smaller values increase precision but raise iteration cost (default 0.0001, same units as the curve’s X axis). | |
| Number Of Iterations | numberof_iterations | scalar | 100 | Maximum number of hill-climbing iterations to perform before stopping; increase beyond the default of 100 for wider or finer search windows. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_hill_climbing_output_1 | curve_hill_climbing_output_1 | scalar | Scalar X-axis value at which the optimal (minimum or maximum) Y value was found on the input curve. |
