Abstract: A novel and powerful fluence and beam orientation optimization package for radiotherapy optimization, called PARETO (Pareto-Aware Radiotherapy Evolutionary Treatment Optimization), makes use of a multi-objective genetic algorithm capable of optimizing several objective functions simultaneously and mapping the structure of their trade-off surface efficiently and in detail. PARETO generates a database of Pareto non-dominated solutions and allows the graphical exploration of trade-offs between multiple planning objectives during IMRT treatment planning PARETO offers automated and truly multi-objective treatment plan optimization, which does not require any objective weights to be chosen, and therefore finds a large sample of optimized solutions defining a trade-off surface, which represents the range of compromises that are possible.

Abstract: A computer identifies a storage element in a simulation model of an integrated circuit design that, during simulation of the integrated circuit design using the simulation model, is subject to having its value forced. In response to identifying the storage element, an indication of the storage element and the associated clock signal are stored in a database. In response to receiving an input indicating the value of the storage element is to be forced during simulation, a determination is made by reference to the database whether or not forcing of the value is mistimed with reference to the associated clock signal. In response to a determination that the forcing of the value as indicated by the input is mistimed with reference to the associated clock signal, an indication that forcing of the value is mistimed is output.
