| org.apache.commons.math3.fitting.leastsquares | This package provides algorithms that minimize the residuals
 between observations and model values. | 
| org.apache.commons.math3.optim | 
  Generally, optimizers are algorithms that will either
   minimizeormaximizea scalar function, called theobjective
  function. | 
| org.apache.commons.math3.optim.nonlinear.vector | Algorithms for optimizing a vector function. | 
| org.apache.commons.math3.optim.nonlinear.vector.jacobian | This package provides optimization algorithms that require derivatives. |
