sol3 Algorithm

The sol3 Algorithm is a cutting-edge, decentralized algorithm designed to optimize the management of renewable energy resources, such as solar and wind power. It combines artificial intelligence, machine learning, and blockchain technology to create a highly efficient and secure system for managing and distributing clean energy. By analyzing vast amounts of data from multiple sources, the algorithm can predict and optimize energy production and consumption, ultimately reducing waste and increasing the overall efficiency of the renewable energy grid. In addition to optimizing energy use, the sol3 Algorithm also fosters a more democratic and transparent energy market. By leveraging blockchain technology, it enables peer-to-peer energy trading, allowing consumers to buy and sell excess energy directly with each other. This not only empowers individuals and communities to take control of their energy needs but also promotes the growth of renewable energy infrastructure. Furthermore, the sol3 Algorithm's decentralized nature ensures that the system remains secure and resistant to manipulation, providing a reliable and trustworthy platform for the future of renewable energy management.

Problem:
Each new term in the Fibonacci sequence is generated by adding the previous
two terms. By starting with 1 and 2, the first 10 terms will be:

    1,2,3,5,8,13,21,34,55,89,..

By considering the terms in the Fibonacci sequence whose values do not exceed
n, find the sum of the even-valued terms. e.g. for n=10, we have {2,8}, sum is
10.
