param4

Param4 is a software library designed for parameter estimation and optimization in scientific and engineering applications. It is particularly well-suited for problems involving complex models with a large number of parameters. The library is written in C++ and provides a flexible and efficient framework for defining and solving optimization problems.

One of the key features of Param4 is its support for various optimization algorithms, including gradient-based methods, derivative-free algorithms, and hybrid approaches. This versatility allows users to choose the most appropriate method for their specific problem, balancing computational efficiency and accuracy.

Param4 also includes tools for sensitivity analysis, which helps users understand the impact of different parameters on the model's output. This can be particularly useful in applications where the model's behavior is sensitive to certain parameters, and identifying these parameters is crucial for further analysis or model refinement.

The library is designed to be user-friendly, with a clear and concise API that makes it easy to integrate into existing projects. It also includes extensive documentation and examples, which can help new users get started quickly.

Param4 is open-source and available under the MIT license, making it accessible to a wide range of users. The library has been used in various applications, including physics, chemistry, and engineering, demonstrating its versatility and robustness.
