constrained optimization of quadratic function
I am using the alabama package to optimize a non-linear constrained optimization problem.
The problem is:
minimise: -(0.653*x[1]+ 0.234* x[1]*x[1]+ 0.437 * x[2] + 0.769 * x[3]
+0.453 * x[4] + 0.744 * x[5] + 0.476 * x[5]* x[5])
The equality…

Ways of ensuring parameters 'sum to one' during function minimisation
I'm trying to perform a minimisation where some parameters must sum to one using PyMinuit. I'm wondering if there is a standard method of implementing this kind of thing?
Is it usual to set the function to some large value if the constraint is not…

Which library can efficiently deal with corner solutions in R?
At the moment I'm trying to do a minimization (optimization) problem in R, where I have a vector X1 that I want to approximate through a weighted average of a matrix X2 and a vector of weights w. That means I want to minimize
wg <- function(w)

How to restore bitmap after application minimization?
I have a drawing application. I need the application to recover from minimization (clicking back until the application minimizes). As i understood from several forums the best way and the simplest to do it is by saving the bitmap to a local…

Is it possible to have more than one minimal DFA 's for a regular language?
If we create two DFA's for a language L say DFA A and DFA B. Then, after minimising the DFA's we get their corresponding equivalent minimal DFA's . Is It always the case that both minimal DFA's have same number of states?
I designed 2 DFAs for a…

Why are the optimized solutions different with scipy.optimize.minimize with small variations in initial guesses?
I am working on a detailed code that requires optimization, which I have simplified for the MWE. I am trying to find the optimal value of arg_opt that minimizes the value that is obtained from a different function.
I believe it is a simple error or…

Fitting two functions sharing same parameters to data
Assume that I have two functions describing one phenomena in the same range (x-axis). Both are sharing same parameters, but also can have their own. How can I fit them or minimize the errors to experimental data using SciPy or Lmfit >>AT ONCE<

Can you minimize a Boolean expression having don't care conditions using Boolean algebraic laws?
I have to minimise a boolean expression in SOP form having don't care conditions. I can do this by k-map but can I do this only using Boolean algebraic laws.

Minimize optimization with constraints from multiple sets of options
I am looking for a way to minimize costs with multiple constraints by selecting one option per group out of a large dataset with groups that each contain options. The dataset consists of around 100 groups with 200 options each.
