Detailed Description

Motivation

This class rapresent a full-connection between neuron's 'from' Cluster and neuron's 'to' Cluster. The connections has a weight and are stored in a matrix which the rows are the neuron's 'from' and the columns the neuron's 'to'.

Description

Every connection is weighted, and the weight is memorized into a weight-matrix.
The effective computation of inputs' 'to' is done in the subclasses (DotLinker, NormLinker, etc).

Warning

From 0.7.0 release the update method will become pure-virtual.
