Installation

1️⃣ Clone the Repository

git clone https://github.com/your-username/vicentin.git
cd vicentin

2️⃣ Set Up a Virtual Environment

python -m venv venv
source venv/bin/activate

3️⃣ Install Dependencies

Usage

Heap data structure

# Example: Using the heap data structure
from vicentin.data_structures.heap import Heap

heap = Heap()
heap.insert(5)
heap.insert(2)
heap.insert(8)

print(heap.extract_min())  # Output: 2

Newton's Method

import torch
from vicentin.optimization.minimization import newton_method

def objective(x):
    return torch.sum(x**2)

x0 = torch.tensor([10.0, 10.0])
A = torch.tensor([[1.0, 1.0]])
b = torch.tensor([1.0])

# Backend (Torch) is automatically detected from x0
x_opt = newton_method(objective, x0, equality=(A, b))
print(f"Optimal solution: {x_opt}")
