LeapHybridDQMSampler.min_time_limit(dqm)

Return the minimum time_limit accepted for the given problem.

The minimum time for a hybrid DQM solver is specified as a piecewise-linear curve defined by a set of floating-point pairs, the minimum_time_limit field under properties. The first element in each pair is a combination of the numbers of interactions, variables, and cases that reflects the “density” of connectivity between the problem’s variables; the second is the minimum required time. The minimum time for any particular problem size is a linear interpolation calculated on two pairs that represent the relevant range for the given problem.

Examples

For a solver where LeapHybridDQMSampler().properties[“minimum_time_limit”] returns [[1, 0.1], [100, 10.0], [1000, 20.0]], the minimum time for a problem of “density” 50 is 5 seconds (the linear interpolation of the first two pairs that represent problems with “density” between 1 to 100).
