definition computational complexity applications see also references external links formal mathematical definition[ edit ] the formal definition of the quadratic assignment problem is as follows: given two sets, p ("facilities") and l ("locations"), of equal size, together with a weight function w :...
rear side reflection of thin layers cause interference. absorption inside each layer changes light wave amplitude. both of these phenomenona can be used together to measure the layer thickness and refractive and absorption index n&k of thin layers. after recording the spectra of the sample, a mathematical...
