Then, based on the generated solutions an approximation method is applied to create a computationally inexpensive surrogate problem for the design problem and the surrogate problem is solved in the second stage with an interactive multiobjective optimization method.
Its main benefits are that it is fast and inexpensive; identifies problems before they're coded, elicits more and better, and fosters teamwork and communication.
If fiber can correct the problems, inexpensive optical modems may be an alternative for millions of homes.
Milk crates, which sell in college bookstores for as little as $2 apiece, provide an inexpensive solution to storage problems.
There is some promising work being done on inexpensive cures for common problems: NPR recently reported that DARPA, the defence research agency that played an important role in the development of the internet, is working on implanting devices in the brains of veterans to treat post-traumatic stress disorder and other mental illnesses.
Furthermore, combining existing and future datasets from space and "ground based" observatories is an emerging mode of powerful and relatively inexpensive research to address problems that can only be tackled by the application of large multi-wavelength observations.
Although the assumed PDF method generally gives better results than the Taylor expansion method, the latter may be a promising, computationally inexpensive approach for engineering problems with more complex chemistry.
Especially when inexpensive sensors are used problems could arise due to lacking of coherence of the single measurements; the same data-loggers are often available in a certified version, but as our aim was also the assembling of a inexpensive measurement system, the price of these latter was obviously too high.
If we can't deliver on drinking water, all of whose technical solutions are low tech and relatively inexpensive, more complex organizational problems like global warming are out of reach.
The process and solutions to the identified problems are inexpensive and attainable within a limited time.
