Samplers are processes that sample from low energy states of a problem’s objective function. A binary quadratic model (BQM) sampler samples from low energy states in models such as those defined by an Ising equation or a Quadratic Unconstrained Binary Optimization (QUBO) problem and returns an iterable of samples, in order of increasing energy. A dimod sampler provides ‘sample_qubo’ and ‘sample_ising’ methods as well as the generic BQM sampler method.
TabuSampler sampler implements the MST2 multistart tabu search algorithm
for quadratic unconstrained binary optimization (QUBO) problems
with a dimod Python wrapper.
For a description of the tabu search algorithm, see tabu search.
