VOPy: A Framework for Black-box Vector Optimization

What is VOPy?

VOPy is an open-source Python library built to address noisy black-box vector optimization problems, where the user preferences are encoded with a cone order.

What to do with VOPy?

VOPy includes several pre-implemented algorithms, models, orders, and problems from the literature for black-box vector optimization, allowing users to select and utilize components based on their specific needs. Specifically, you can:

• Use existing black-box vector optimization methods for new problems
• Benchmark novel algorithms with the state-of-the-art
• Utilize a wide range of existing tools in black-box vector optimization
