About Optimisation

Optimisation is the process of finding the best solution to a problem given certain constraints. This calculator uses numerical methods to find the maximum or minimum values of functions.

Key Concepts in Optimisation
  • Objective Function: The function to be maximised or minimised
  • Constraints: Limitations on the possible solutions
  • Feasible Region: The set of all possible solutions that satisfy all constraints
  • Optimal Solution: The solution that gives the best value of the objective function
  • Local vs Global Optima: Local optima are the best in a neighbourhood, while global optima are the best overall
Methods Used
  • Grid Search: Systematically evaluating the function at regularly spaced points
  • Gradient Descent: Finding local minima by moving in the direction of steepest descent
  • Constraint Handling: Penalty methods to handle constraints

Disclaimer: This calculator provides numerical approximations and may not always find the global optimum for complex functions. Results should be verified with analytical methods for critical applications.

What Is the Optimization Calculator?

The Optimization Calculator is an interactive tool that helps you find the maximum or minimum value of a mathematical function involving two variables—commonly denoted as x and y. It supports optimization within defined ranges and under custom constraints, making it useful for analysing a wide variety of problems in Calculus, engineering, economics, and more.

\( f(x, y) = x^2 + 2y - 3xy \)

Key Features

  • Maximise or minimise a custom function of two variables
  • Define specific ranges for variables
  • Add up to three constraints, such as x + y ≤ 10
  • Adjust calculation precision: low (faster), medium, or high (more accurate)
  • View results in a 2D or simplified 3D visual chart
  • Understand critical points using gradient and second derivative analysis

How to Use the Calculator

Follow these steps to get your optimal solution:

  1. Select whether you want to maximise or minimise your function.
  2. Enter your function using variables x and y, e.g., x^2 + y^2.
  3. Set the minimum and maximum values for x and y.
  4. Optionally, input up to three constraints such as x + y <= 10 or x^2 + y^2 = 25.
  5. Choose your desired calculation precision.
  6. Decide if you want a 3D plot view (enabled by default).
  7. Click Find Optimal Solution to see the results.
  8. Use the Reset button to start over.

Why Use This Tool?

This calculator can be a valuable companion for students, professionals, and anyone exploring optimisation problems. It can help you:

  • Visualise how your function behaves over a range of values
  • Experiment with constraints to see their impact
  • Identify optimal values with supporting analysis
  • Check work from Other tools such as a Partial Derivative Calculator or second derivative solver

Frequently Asked Questions

What kind of functions can I enter?

You can input any function using x and y. For example: x^2 + y^2, 3*x - 2*y, or sin(x) + cos(y).

Can I use constraints?

Yes, you can add up to three constraints using inequality or equality symbols: <=, >=, or =.

How accurate are the results?

Results are numerical approximations. For best results, choose "High" precision. This tool complements analytical techniques like solving with a partial derivative solver or checking results using a Directional Derivative Calculator.

Is this the same as taking partial derivatives?

This tool evaluates functions across a grid and refines the result but does include gradient and partial derivative insights. It's useful when paired with a multivariable derivative solver to deepen understanding.

Can I view the solution visually?

Yes, results include a chart that shows how the function value changes. You can view this as a 2D or simplified 3D plot.
