Claim 14:
15. A method for qualitatively simulating spatio-temporal behaviors of a physical system, said method comprising:
specifying a topological structure of the physical system in space-time;
constructing a qualitative spatio-temporal model of the physical system, wherein the qualitative spatio-temporal model of the physical system is expressed by topological semantics based on a Tonti diagram in which qualitative states of physical variable are systematically organized as nodes on the Tonti diagram and governing expressions constraining the qualitative states are symbolically expressed as connections between selected nodes on the Tonti diagram; and
using both the topological structure and the qualitative spatio-temporal model in conjunction with performing spatio-temporal multi-physics qualitative reasoning to simulate the qualitative spatio-temporal behaviors of the physical system as a discrete set of state transitions in space-time.
