# [−][src]Crate argmin_core

Argmin Optimizaton toolbox core

This crate contains the core functionality of argmin. If you just want to run an optimization
method, this is *not* what you are looking for. However, if you want to implement your own
solver based on the argmin architecture, you should find all necessary tools here.

TODOs:

- Provide an example of how to implement a solver

## Traits

ArgminAdd | Add a |

ArgminDiv | (Pointwise) Divide a |

ArgminDot | Dot/scalar product of |

ArgminEye | |

ArgminInv | Compute the inverse ( |

ArgminIter | Main part of every solver: |

ArgminLineSearch | Defines a common interface to line search methods. Requires that |

ArgminLog | Defince the interface every logger needs to expose |

ArgminMul | (Pointwise) Multiply a |

ArgminNLCGBetaUpdate | Every method for the update of beta needs to implement this trait. |

ArgminNorm | Compute the l2-norm ( |

ArgminOp | This trait needs to be implemented for every operator/cost function. |

the |

methods. Requires that |

ArgminWeightedDot | Dot/scalar product of |

ArgminWrite | Every writer (which is something that writes parameter vectors somewhere after each iteration) needs to implement this. |

ArgminZero | Return param vector of all zeros (for now, this is a hack. It should be done better) |
