What is a routing problem?
According to Ann Campbell from University of Iowa, the objective of routing problems in transportation is “to minimize the distribution costs during the planning period without causing stockouts at any of the customers”.
The most general case can be modelized by the Vehicle routing problem that broadly speaking consists on:
). I missed the boat, though, since it has been replaced by the PV-GS500, which is not the same camcorder. So I opted for this Sony. This camcorder takes excellent video, make no mistake; just check the reviews on CNET and especially Camcorderinfo for more technical information on this. After all my research, I feel that this is the best overall family camcorder because it is very user-friendly for all the technophobes out there, but it also allows some manual control for the user that wants to explore more advanced (read: manual) features. Word of caution: these more advanced features are accessed via LCD menu, and do not have one-push buttons or rings like the PV-GS400 or other higher end prosumer cameras, but rearranging the LCD menu and putting controls like spot focus, spot meter, focus, exposure, and white balance in the first screen of the p-menu makes this little (literally) camera far more usable. The review on camcorderinfo made it sound like rearranging the LCD menu was a job for the gods of technology. It is not. I read the manual in a half hour, and after another half hour all the menu items had been sorted based on my preferences: it’s just a matter of pressing p-menu on the LCD, scrolling all the way down, selecting the p-menu options, pressing the Sort button, and then moving the buttons around according to your preference. Now, it is really important to move all the buttons I mentioned above (spot focus and meter, focus, exposure, and especially white balance) to the first screen if you want to keep your sanity. The reason is simple: you will be using some of these features a lot. White balance, for example, offers four options: auto, outdoor, indoor, and one-push. If you want faithful reproduction of color, take my advice: use one-push. I noticed that the indoor option takes an orangey video, but if you get a white/grey card (you should, it’s about $18 for a Kodak one here on Amazon) or use any white surface (the back of a notebook for example) under the same light as your subject, frame it with your LCD and press one-push under the white balance menu option, your video will have a perfect color reproduction. Do you see why you want to have white balance in the first p-menu screen?
