optimisation and solutions
 

hey i come across a lot of papers nowadays on optimisations and not on solutions does it mean that the area of solutions of navierstokes and other equations saturated with research and results? i am eager to ask this cause i am a budding engineer and am concerned about my future

Re: optimisation and solutions
 

It means that doing a good optimisation requires knowledge about the problem, nothing more. Many researchers, sorry for those who feel offended, tend to be too ambitious and choose models that are too time consuming to do a proper optimisation or it also happens that the model is good but they don't know enough different optimisation methods to choose the right one for their application. Often they try to compensate a lack of knowledge with brute force calculations.

At the end they publish any result that came out simply because the time is up, even if they didn't finish it.

That's all, it doesn't say anything about the quality of the solver, the quality of the optimisation model or the saturation of anything, what you see many times is an unfinished project that they felt forced to publish by their chief or anyone who's paying them. (Wouldn't you do the same?)

Well Prapanj I angry with you but us long us there isn't a pure mathematic formula for calculating the quality of the optimizer, the right optimization method choose is going to lye on the experience of the researche.
