World Community Grid (WCG) is a non-profit organization that harnesses the unused computing power of personal computers and smartphones to perform scientific research that addresses some of the world's greatest challenges. WCG provides a platform for scientists to access the computing power they need to perform complex calculations, simulations, and data analysis that would otherwise be too expensive or time-consuming to complete using traditional supercomputing methods.

Wicked problems are complex social and environmental problems that are difficult to solve due to their interrelatedness, uncertainty, and conflicting values.
