An optimization problem of using imperfect objects, such as defective analog and digital components, was discussed. A combination or a subset was obtained that optimized the average error or the number of working transformations. Results using statistical physics showed that perfect, or near-perfect devices could be constructed and the remaining objects could be recycled efficiently with zero net wastage.
