what is the function constroptim which optimization is suitable for equality constraints what is the library used for an optimization function what is constrained optimization what type of library is quadprog for optimization what constraint is a kl divergence function which library does optimization use what is the constraint on optimization function what is constraint optimization what library should i use for minimizing the function kl divergence in r which constraint optimization library to use what library is used for equality and inequality constraints which library can be used for equality and inequality constraints? what is the constraint optimization library why use constrained optimization is kl divergence a function what is constrained optimization what is quadprog what is the constrained optimization library? what is the constraint optimization library
