Im currently working on a project of mine with sagemath.
Basiaclly what im trying to optimize is a non-linear function under some constraints.
My function to maximize is:
N(x,y) = ((10- 2*x + y)/(1.25 + y)) * ((20 - 2*x + y)/(1.25 + y))
where the constants in this function are user inputs and x,y the variables to optimize under the following constraints:
(y - 0.003) + 2 * (x - 0.03) < 1.25,
x > 0,
y > 0
I tried defining the constraints as c1 to c3 and inputting them like this:
minimize_constrained(N_cells, [c_1,c_2,c_3],[0,0])
But unfortunately it gives me a Not Implemented Error and im stuck.Tue, 10 Dec 2019 13:15:21 +0100https://ask.sagemath.org/question/48985/problem-with-minimize_constrained-function/Comment by vdelecroix for <p>Hello everyone. Im currently working on a project of mine with sagemath.
