TerraVision> Express> Overview
Historical Background of EXPRESS
In 1965 Dr. Lerches and Dr Grossmann developed a pit optimisation system (the LG) using a mathematical concept called Graph Theory. This system has become the basis of many pit optimisers available today (eg. Whittle, MineMap, and others).
Twenty years later, Graph Search Theory was developed to accommodate the massive data sets required by expert systems for automated decision making. Now, ten years further on, the Optimum Planit research team, lead by Dr Tim Gill with the aid of Industry, developed Dynamic Graph Search Theory to accommodate dynamically changing, massive data sets to bring you EXPRESS.
