Patent ID: 8886497

Claim:
A machine implemented method comprising: iteratively solving, by a machine having a processor system including one or more processors and a memory system including a memory system having at least one or more nontransient-machine readable media, a set of equations, each equation being a result of taking a derivative of an action integral, which is an integral of a Langrangian with respect to time, the derivate of the action integral being a derivative with respect to a parameter of a Lagrangian density associated with the Lagrangian, the Lagrangian density has a dependence on the parameters, each parameter of the Lagrangian density being part of a set of parameters of a parameterized potential function, the dependence of the Lagrangian density on the set of parameters being that of a representation of the Lagrangian density in terms of the potential function; prior to the iteratively solving, the set of parameters include parameters that have values that are not known; the iteratively solving of the set of equations determines solution values for the parameters; computing, by the processor system, a value representative of an error associated with a current iteration of the iteratively solving; and if the value representative of the error for the current iteration is on an opposite side of a predetermined threshold compared to the value representative of the error for a prior iteration, ending the iteratively solving.
