| Package | Description | 
|---|---|
| org.hipparchus.analysis.integration | Numerical integration (quadrature) algorithms for univariate real functions. | 
| org.hipparchus.ode | 
 This package provides classes to solve Ordinary Differential Equations problems. | 
| org.hipparchus.optim | 
  Generally, optimizers are algorithms that will either
   minimizeormaximizea scalar function, called theobjective
  function. | 
| org.hipparchus.optim.nonlinear.vector.leastsquares | This package provides algorithms that minimize the residuals
 between observations and model values. | 
| org.hipparchus.util | Convenience routines and common data structures used throughout the Hipparchus library. |
