Golden Section Search Solver

Find the minimum of any unimodal function without derivatives

Configuration

Function f(x)

Quick Insert:

💡 Formatting Guide:

x^2 Power/Exponent (use x^□ button or type ^)

2x Implicit multiplication (no asterisk needed)

7/8 Simple fraction (auto-converts)

\sqrt then type – Square root

\frac then type – Proper fraction

\sin \cos Trig functions

ln(x) means natural logarithm (base e).

⚠️ Golden Section Search assumes your function is unimodal in [a, b]. If not, the result may be a local minimum/maximum, not the global one.

Search Interval

Left Bound (a)

Right Bound (b)
