 //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.
