Abstract: A user interface (UI), data structures and algorithms facilitate programming, analyzing, debugging, embedding, and/or modifying problems that are embedded or to be embedded on an analog processor (e.g., quantum processor), increasing computational efficiency and/or accuracy of problem solutions. The UI provides graph representations (e.g., source graph, target graph and correspondence therebetween) with nodes and edges which may map to hardware components (e.g., qubits, couplers) of the analog processor. Characteristics of solutions are advantageously represented spatially associated (e.g., overlaid or nested) with characteristics of a problem. Characteristics (e.g., bias state) may be represented by color, pattern, values, icons. Issues (e.g., broken chains) may be detected and alerts provided.

Abstract: A nursing bottle support for freeing the hands of a person carrying an infant while feeding the infant from the bottle comprises a foldable, non-resilient hook which wraps around the person's neck with an adjustable shank lying against the person's chest. A clasp made of an open-ring of elastomeric material is rotatably mounted at the end of the shank, and can be positioned in a variety of orientations to direct the bottle toward the mouth of the feeding infant.

Abstract: A nursing bottle support for freeing the hands of a person carrying an infant while feeding the infant from the bottle comprises a bendable, non-resilient hook which wraps around the person's neck with an expandable shank lying against the person's chest. A clasp made of an open-ring of elastomeric material is rotatably mounted at the end of the shank, and can be positioned in a variety of orientations to direct the bottle toward the mouth of the feeding infant.
