1. A method comprising: simulating a self-assembly block copolymer feature, wherein the simulated block copolymer feature comprises a first domain comprising a first polymer type and a second domain comprising a second polymer type; calculating a minimum energy position of the first domain within the simulated block copolymer feature, wherein the minimum energy position is the position of the first domain at a first energy state of the block copolymer feature, the first energy state being substantially at a minimum energy; simulating the application of a potential to the block copolymer feature, wherein the potential causes the position of the first domain to be displaced from the minimum energy position; simulating release of the potential, thereby allowing the energy of the block copolymer feature to relax to substantially the minimum energy; recording a plurality of energies of the block copolymer feature as the block copolymer feature relaxes to substantially the minimum energy; recording at each of the plurality of energies a displacement of the first domain from the minimum energy position; calculating, from the recorded energies of the block copolymer feature and the recorded displacements of the first domain, a probability distribution indicating a probability of the first domain being displaced from the minimum energy position; and calculating, from the probability distribution, an uncertainty in the position of the first domain within the block copolymer feature.
