You can also use manim the python library to visualise math and graphs. Also I think in f(x) you will have to integrate it with -infinite to positive infinite to make the calculation with more precision. Although I can be wrong since I am rusty with my integration skills..

@TokyoEdTech 3 жыл бұрын

I can't speak to the manim library but it sounds useful. EDIT: We need to take the derivative and solve for 0 to find the minimum. However, the scipy library is used for machine learning and it figures out the values using its own methods.

Hey is there a way to make it so that the values only use integers for x? For example with the fence: say you can only build 1 meter fence blocks.

Hi - I have a function with 6 inputs, 4 of which I want it to change values for optimisation (call them a,b,c,d), and the other two I need it to ignore, one of them is a simple scalar (t=0.01 say so i could set a bound of (0.01,0.01) to force it to have that value), but the other (X) is a huge list (its the y values of an xy plot, there are 100,000 values) so i cant simply set bounds for it like (1,1), as its an array. The function uses X and t, but I only want to change the a,b,c,d in maximising. How can i set this up so that it can ignore X and t? Its like, I only want to pass it guess values for *some* of the variables, but if I dont provide them all it will fall over right? Any help appreciated :D

@TokyoEdTech 3 жыл бұрын

That's a tough one - not 100% sure. Pretty much all I know is what I put in the video. The only thing you can try is to use lists for the variables that change and tuples for the ones that don't. Just a guess though. Good luck!

@TokyoEdTech 3 жыл бұрын

I'm not really sure what you mean - I think what optimize does is finds the lowest result of an equation.

Hey, love the video, just have one question. If I am returning multiple variables in a function that I want to minimize, how do I do that ?

@TokyoEdTech 3 жыл бұрын

I'm not sure how you'd go about that - there's probably a way, but I haven't tried it. This is really all I know about the subject. Sorry!

@0alcoholism2 3 жыл бұрын

@@TokyoEdTech dont worry about it lol, I did find a work around tho. If I want to maximise one variable and minimize the other, I just set a separate variable which is the division of the maximised variable and the minimized one. then I maximize that new variable. I also include a print statement in the function to see the values of the 2 variables. To maximise or minimise 2 variables, I just add them and then do the same process.
