Abstract: Embodiments disclosed herein provide methods, systems, and computer program products for determining layouts of objects in environments. An example method includes, by a processor, receiving, in memory, (i) an indication of the set of objects, (ii) an indication of characteristics of the environment, and (iii) one or more criteria. The received indication of the set of objects and the one or more criteria are used to determine a priority order of each object in the set of objects. In turn, the layout of the set of objects is determined by, in the determined priority order, iteratively selecting a location for each object.

Abstract: An aqueous liquid detergent composition containing a nonionic surfactant, a builder, a particular hydroxypropyl methylcellulose ether and optionally an anionic surfactant is disclosed having unusual stability, especially at low temperatures. The hydroxypropyl methylcellulose is characterized as having 28-30% methoxyl and 7-12% hydroxypropyl substitution with molecular weight from 5-250 cps nominal viscosity in 2% aqueous solution at 68.degree.
