What is the primary difference between discrete and continuous optimization?
What is the primary difference between discrete and continuous optimization?
Discrete optimization deals with variables that can take on specific values, while continuous optimization involves variables that can take on any value within a range.
Define a constrained optimization problem.
Define a constrained optimization problem.
A constrained optimization problem includes restrictions or limitations on the variables that must be satisfied while seeking to optimize an objective function.
Explain the concepts of local and global maxima.
Explain the concepts of local and global maxima.
A local maximum is the highest value in a neighborhood of points, whereas a global maximum is the highest value overall across the entire feasible region.

Study Notes
Engineering Applications of Optimization
- Optimization is crucial in various engineering fields.
Statement of an Optimization Problem
- Optimization problems involve finding the best solution from a set of possible options.
Discrete and Continuous Optimization
- Discrete optimization: Deals with problems where the variables can only take on specific, distinct values (e.g., integers).
- Continuous optimization: Involves variables that can take on any value within a given range.
Constrained and Unconstrained Optimization
- Constrained optimization: Has restrictions (constraints) on the variables' values.
- Unconstrained optimization: No limitations on the variables' values.
Local and Global Maxima and Minima
- Local maximum: A point where the function's value is greater than or equal to all nearby points.
- Global maximum: A point where the function's value is greater than or equal to all points in the entire defined region.
- Local minimum: Opposite of local maximum.
- Global minimum: Opposite of global maximum.
Monotonic and Unimodal Functions
- Monotonic function: A function that is either always increasing or always decreasing.
- Unimodal function: A function that has only one peak or valley within a given interval.
Formulation of Optimization Problems
- Optimization problems can be expressed as mathematical programming problems.
