| //End of 2018.// Constructed a numerical algorithm which can provably find a numerical description of any protocol from its point game description. Effectively, this allows one to construct explicit (although numerical) protocols with arbitrarily small biases (in the absence of noise). \\ | //End of 2018.// Constructed a numerical algorithm which can provably find a numerical description of any protocol from its point game description.

This will hopefully result in the complete description of an explicit weak coin flipping protocol with ε tending to zero. \\ | + | //End of 2019.// Found analytic expressions for the unitaries corresponding to Mochon's constructions which yield arbitrarily small bias. \\ |
