Easy convex optimization in python with cvxpy

certainly! convex optimization is a subfield of optimization that deals with problems where the objective function is convex and the feasible region is a convex set. this type of optimization is important in many fields, including machine learning, finance, and engineering. in python, one popular library for solving convex optimization problems is `cvxpy`.

### installation

first, you need to install the `cvxpy` package if you haven't already. you can do this using pip:

### basic concepts

in convex optimization, we typically want to minimize a convex objective function subject to some constraints. the general form of a convex optimization problem can be expressed as follows:

\[
\text{minimize } f(x) \\
\text{subject to } g_i(x) \leq 0 \quad \forall i \\
h_j(x) = 0 \quad \forall j
\]

where:
- \( f(x) \) is the objective function (convex function).
- \( g_i(x) \) are the inequality constraints (convex functions).
- \( h_j(x) \) are the equality constraints (affine functions).

### example problem

let's solve a simple convex optimization problem:

**problem**:
minimize the function \( f(x) = (x - 2)^2 + (y - 3)^2 \)
subject to the constraints:
- \( x + y \geq 5 \)
- \( x \geq 0 \)
- \( y \geq 0 \)

this problem represents the squared distance from the point (2, 3) to a feasible region defined by the constraints.

### implementation using cvxpy

here’s how to implement this in python using `cvxpy`.

### explanation of the code

1. **importing libraries**: we import the `cvxpy` library as `cp` and `numpy` for numerical operations.

4. **constraints**: we define the constraints as a list of inequalities and non-negativity conditions.

5. **problem definition**: we create a `problem` instance by passing the objective and constraints.

6. **solving the problem** ...
