Given a densely-connected, double and weighted-directed, graph A, a natural number x>1, a natural number t > (the minimum weight of any edge of A), we will consider a subgraph B with the following properties:
- contains all nodes in A
- only one direction of any edge is part of B
- all these edges have a weight equal or greater than t
- there is no cycling in any direction
- each node has at least x incoming edges
- each node has at most x outgoing edges
We may assimilate the following:
- A: the real-world trust network
- B: the traceable trust network
- x: the trust breadth
- t: the trust level
Interesting properties:
- Ability to uniquely determine a node where a breach of trust happens
- Resistance to catastrophic failure and abstraction of compromised nodes – demonstrated here
To do:
- Determine the optimal values of x and t
- Solve for exceptions (sparsely-connected graph)
