How to put a fixed specific quantity of items to be allowed in a bin Question: I have found this code for a bin packing problem in Google OR-tools. https://developers.google.com/optimization/bin/bin_packing#python_3 However, it does not have a volume constraint. What if the total quantity/number of items packed in a bin (which is printed in the output …
fitting step function with variation in the step location with scipy optimize curve_fit Question: I am trying to fit x y data which look something like x = np.linspace(-2, 2, 1000) a = 0.5 yl = np.ones_like(x[x < a]) * -0.4 + np.random.normal(0, 0.05, x[x < a].shape[0]) yr = np.ones_like(x[x >= a]) * 0.4 + …
How to pass arguments to callback function in scipy.optimize.differential_evolution Question: I am using differential_evolution from scipy.optimize for my optimization problem. My optimizer takes some arguments for the optimization. Code – res = optimize.differential_evolution(objective,bounds,args=arguments,disp=True,callback = callback_DE(arguments)) I also have a callback function. I want to send my arguments to my callback function and that is where …
Is there any quadratic programming function that can have both lower and upper bounds – Python Question: Normally I have been using GNU Octave to solve quadratic programming problems. I solve problems like x = 1/2x’Qx + c’x With subject to A*x <= b lb <= x <= ub Where lb and ub are lower …
