A numerical method used to find the approximate solution to a problem by repeatedly refining an initial estimate.

A single step in a computational process where the result of one step is used as input for the next.

A process where successive iterations of a calculation get increasingly closer to a fixed point (final solution).

A method of finding the input values (x-values) for which a function (f(x)) equals zero.

A method of finding a specific point within a sorted list by repeatedly dividing the search interval in half.

A function within the SciPy library used to find the roots of a function, solving equations numerically.

A starting value to be refined by iterated calculations in methods like relaxation.

A point in space where the combined gravitational forces of two massive bodies (e.g., Earth and Moon) on a smaller object cancel out.

A method to find the position where the net gravitational forces are balanced.

A function in Python used to find roots of equations.

A point in space between the Earth and the Moon where the gravitational forces of Earth and Moon are balanced.

The numerical value in meters measuring the distance of an object (or calculated point) from Earth.

An optimization method used to find the maximum or minimum of a unimodal function within a given interval.

A function that has only one maximum or minimum within a given interval.

The range within which we search for the maximum or minimum of the function.

The acceptable difference between the final values of x1 and x4, indicating the precision of the result.

When the function value at T2 is greater than the function value at T3, the maximum is likely closer to the left half of the current interval.

In this case, the search interval is shifted to the left by moving T3 and T4 down.

When the function value at T2 is less than or equal to the function value at T3, the maximum is likely closer to the right half of the current interval.

Here, the search interval is shifted to the right by moving T1 and T2 up.

The formula used to calculate the intensity of visible light emitted by a blackbody at a specific wavelength.

An idealized object that absorbs all electromagnetic radiation incident upon it and emits radiation at all wavelengths.

A law of physics that describes the spectral radiance of electromagnetic radiation emitted by a blackbody at a given temperature.

A relation between the temperature of a blackbody and the wavelength at which it emits the most intense radiation.

Determining the best solution from a set of possible solutions, often by maximizing or minimizing a function.

A numerical optimization algorithm for finding the maximum or minimum of a function within a given interval.

A repeated application of a process or rule to refine a solution or search for a maximum/minimum point.

The process where the results of repeated iterations of an algorithm approach a specific value (the optimal solution)

A mathematical function with six local maxima and minima. This function is often used to test optimization algorithms.

A grid created by combining two arrays. It is used to represent a 2D grid where each point has coordinates (x, y) taken from the original arrays.
