@ector/state NPM

`@ector/state`

@ector/state allows activation value propagation within a @ector/concept-network.

Usage

const conceptNetwork = require('@ector/concept-network');
const cns = require('@ector/state');

let cn = conceptNetwork.addNode({}, 'ECTOR');
cn = conceptNetwork.addNode(cn, 'knows');
cn = conceptNetwork.addNode(cn, 'Achille');

cn = conceptNetwork.addLink(cn, 'ECTOR', 'knows');
cn = conceptNetwork.addLink(cn, 'knows', 'Achille');

let cns = cns.activate({}, 'ECTOR');
cns = cnsPropagate(cn, cns);

will give

{ "ECTOR": { "value": 59.500004166625004, "age": 1, "old": 100 },
  "knows": { "value": 63.40844023393148, "age": 0, "old": 0 } }
