Caption: This chart shows a completed cycle of the genetics-based computer model. The "optimum" point represents the best possible combination of factors that will achieve reduced emissions of both soot and nitric oxide. Those two pollutants are targeted for major reductions by the U.S. Environmental Protection Agency. The "baseline" represents the best existing technology.
