A well-designed algorithm can significantly improve the speed and accuracy of the calculator, enabling it to handle complex multivariable functions with ease. In this section, we will delve into the importance of an efficient algorithm and explore two algorithms that achieve this goal.

The Gradient Descent algorithm is a widely used optimization technique that iteratively updates the parameters of a function to minimize the cost function. It works by moving in the direction of the negative gradient of the cost function, which is computed using the partial derivatives of the function with respect to each variable.
At each iteration, the Gradient Descent algorithm updates the parameters as follows:
- Compute the gradient of the cost function with respect to each parameter.
- Update the parameters using the following equation:
- Repeat the process until convergence or a specified number of iterations is reached.
\[ \theta_i = \theta_i – \alpha \cdot \frac\partial L\partial \theta_i \]
The Gradient Descent algorithm has several strengths, including:
*
Efficiency: The Gradient Descent algorithm is relatively fast and can handle large datasets.
*
Flexibility: The algorithm can be applied to various types of problems, including classification and regression.
However, the Gradient Descent algorithm also has some weaknesses, such as:
*
