📐 Mathematical Foundations

Optimization Theory

The Constrained Optimization MCP Server implements solutions for various classes of optimization problems:

Linear Programming (LP)

$$\min_{x} c^T x \quad \text{subject to} \quad Ax \leq b, \quad x \geq 0$$

Quadratic Programming (QP)

$$\min_{x} \frac{1}{2}x^T Q x + c^T x \quad \text{subject to} \quad Ax \leq b, \quad x \geq 0$$

Convex Optimization

$$\min_{x} f(x) \quad \text{subject to} \quad g_i(x) \leq 0, \quad h_j(x) = 0$$

Where $f$ and $g_i$ are convex functions.

Constraint Satisfaction Problems (CSP)

Find $x \in \mathcal{D}$ such that $C_1(x) \land C_2(x) \land \ldots \land C_k(x)$

Portfolio Optimization (Markowitz)

$$\max_{w} \mu^T w - \frac{\lambda}{2} w^T \Sigma w \quad \text{subject to} \quad \sum_{i=1}^{n} w_i = 1, \quad w_i \geq 0$$

Where:

$w$: portfolio weights
$\mu$: expected returns
$\Sigma$: covariance matrix
$\lambda$: risk aversion parameter

Constraint Satisfaction Problem

# Solve a simple arithmetic constraint problem variables = [ {"name": "x", "type": "integer"}, {"name": "y", "type": "integer"}, ] constraints = [ "x + y == 10", "x - y == 2", ] # Result: x=6, y=4

Portfolio Optimization

# Optimize portfolio allocation assets = ["Stocks", "Bonds", "Real Estate", "Commodities"] expected_returns = [0.10, 0.03, 0.07, 0.06] risk_factors = [0.15, 0.03, 0.12, 0.20] correlation_matrix = [ [1.0, 0.2, 0.6, 0.3], [0.2, 1.0, 0.1, 0.05], [0.6, 0.1, 1.0, 0.25], [0.3, 0.05, 0.25, 1.0], ] # Result: Optimal portfolio weights and performance metrics

Linear Programming

# Production planning problem sense = "maximize" objective_coeffs = [3.0, 2.0] # Profit per unit variables = [ {"name": "product_a", "lb": 0, "ub": None, "type": "cont"}, {"name": "product_b", "lb": 0, "ub": None, "type": "cont"}, ] constraint_matrix = [ [2, 1], # Labor: 2*A + 1*B <= 100 [1, 2], # Material: 1*A + 2*B <= 80 ] constraint_senses = ["<=", "<="] rhs_values = [100.0, 80.0] # Result: Optimal production quantities
