inlineinherited

Optimize for minimum value of the provided objectfunction.

Parameters

objectfunction	The function that will be searched for the minimum return value.
initvals	A tuple with the initial values for the search
bounds	A parameter pack with the bounds for each dimension.

Returns

Returns a Result<Args...> structure. An example call would be: auto result = opt.optimize_min( [](tuple<double> x) // object function { return std::pow(std::get<0>(x), 2); }, make_tuple(-0.5), // initial value {-1.0, 1.0} // search space bounds );
