Lorenz’s discovery was an important moment in the development of modern chaos theory. Complexity Theory & The El Farol Bar problemThis scenario is outlined in theThe El Farol bar in Santa Fe, New Mexico. This scenario is outlined in the El Farol Bar problem , a famous conundrum in complexity theory. These problems still remain a mystery, but by using ideas from chaos and complexity theory, maybe they won’t stay that way for much longer. What would come of these efforts is the science of complex systems.Here are a few short stories behind some of the biggest ideas in chaos and complexity theory.
