Abstract: A method, computer system and computer program product for providing a computer simulation that provides advance notification of expected events or states, comprising running a first computer simulation; running a second computer simulation corresponding to said first simulation, said second simulation having progressed further than said first simulation; and using said second computer simulation to provide information representing expected future events in said first simulation. A first computer simulation may be based on a model of a simulated system, said model having a plurality of state variables. Input data from a first user input interface may represent user interaction with said first computer simulation, while input data from a second user input interface may represent the extent to which a condition should be present in said simulation.
