Question about multy-threads in alglib.nleqsolver (C#).
I have two (or more) Backgroundworker-based objects and hence work with two independent threads.
But a delegate - ndimensional_func(double[] arg, ref double func, object obj) - has the "ref" link. My results are sometimes "intersects" because of reference "func" can be common.
Using of two or more references ("alglib2x.dll"...) is impossible in .net, so: is any way to "split" nleqsolver-based calculations?

As long as different threads work with different instances of nleqsolver class, everything is thread-safe. If you want to launch two solvers in parallel, create two instances. Does it solve your problem?

Of course, there two instances were been created... But I found that the reason of the problem was in incorrect boundary (input) parameters transmittion : there were data from public static fields of mainform. When standard object DoWorkEventArgs of the Backgroundworker is used for parameters setup, it works Ok and it is possible to load a multi-core processor. Thanks!
