# How to optimise a definite integral?

In the attached image, I want to optimize the function Dt, as I know the end result of the integral. I have expressions for k1 and k0 in terms of k2 and N, and it is k2 and N that I would like to optimize. They have constraints, needing to be between certain values. I have it all setup in my code, but I am just unaware of how to tell the genetic alogrithm to optimize an integral function? Is there something I'm missing here?

EDIT: Usually, the integration is completed numerically on MATLAB, I don't actually know what the analytical result is.

How to code this equation....could anyone help me ..

im getting errors in contraints

%LOGICAL Convert symbolic expression to logical array

% Y = LOGICAL(X) converts each element of the symbolic

% array X into the value true or false.

% Symbolic equations are converted to true

% only if the left and right sides are identically

% the same. Otherwise the equation is converted to

% false. Inequalities which cannot be proved will

% throw an error.

the equation is

Did you even read what sloppydisk posted?

This is not an answer to the original question. If you have a question, make a new post for it instead of putting it in some random place.

EDIT: Oh I see this isn't the first time. Walter has already given you an answer on this. If you have a question, ask a complete, descriptive question without concealing the sum of your efforts to date, and without dumping off-topic things where they don't belong. Doing this only makes it less likely that anyone will see your question, let alone understand it or answer it. Hiding questions and omitting information is contrary to the basic purpose of communication.
