I am trying to write a Python script file which analyses data in an
iterative manner. During each iteration, I wish to utilise the Solver
function in Excel to perform some constrained, non-linear fitting to
the data. I have a VBA macro which runs the Solver, and am using
self.xlapp = win32com.client.dynamic.Dispatch("Excel.Application")
..

has anyone every used the solver add-in for Excel? it allows you to solve
linear and non-linear problems given certain conditions. I was wondering if
something like this exists already in .NET? In an application I would like
to solve a model with 500 variables. Excel-Solver can do this but I want to
do it all in code.
any thoughts are appreciated!

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
