Optimisation Definition and 63 Threads

Hello I have a function which is very similar in shape to a Gaussian, except it is not a distribution and it is not analytic, so I can at best calculate a single point on the curve at a time. (In general it is a convolution of different distributions but this is not important). I need to find...

Hello I am trying to speed up a code which performs a number of tasks on a set of data. I am wondering if there are any resources on general rules and principles that can be used to speed up calculation times? I am having a real problem when there appear to be more than one way to code...

Quick question, I am taking this analog design class and the class includes a project which requires design optimisation using either excel,or mathcad Has anyone used excel to optimise the design? If yes, can you please guide me to the resource on how to setup excel to optimise or give...

for the problem: - find H and W as functions of y0, E (having a method to solve for y0 = const, E=const is fine, too) such as product HW is max, under constraint: HW/(y0 + H) < E if numeric, the method should be fast. any suggestions?

Find the critical point(s) for the function: f(x,y)=5x^2-3xy+y^2-15x-y+2 and classify it. Can anyone help? Thanks.

Homework Statement A right angled triangle with sides of length a, b and 2r is trapped within a semi-circle of fixed radius r. Given that all three vertices are on the semi-circle, find the values of a and b that will maximise the area of the triangle...

Homework Statement The first problem is a related rates question: A swimming pool if 5m wide and 25m long, 1m deep at the shallow end and 4.5 deep at the deepest point. A cross section is shown in the figure below. The pool is being filled at a rate 0.5m^3/hr. Use calculus techniques to...

Hello, I would be interrested to learn if there are some (new) open source and/or possibly free librairies available for nonlinear optimisation and equations solving. I would be mostly interrested in modern languages like java or C# . "Clean" fortran could also be interresting as long as...

Hey I am given the set volume for a cylindrical container and separating pricing for the material used to construct the container, the base and the side wall. The ends of the container cost $0.05 per cm2 and the side walls $0.04 cm2, and the volume is 400 mL. The question asks: What is the best...

G'day guys, got this question out of Step-by-step calculs by J.G. graham for those of you who have the book. I've had quite a bit of a play around with it but it doesn't seem to be going anywhere i end up with a few equations which have 3 variables, and i can't reduce it to two. Okay...

I have been given a problem of taking an object (I used a Cornflakes Box) and finding the optimal surface area compared to its volume (volume and ratio between sides constant) I got: Cornflakes Box : Length = 25cm Height = 36 cm Width = 9 cm Optimal Surface area box: Length = 17.3...
