This leads to an expression for the elasticity of the risk curve, 1 q[x] ∂ ∂x q [x] x= c⁎ E = d 1− c⁎ E (6) i.e. the relative change of the risk curve necessary for an equilibrium scales linearly with the number of players d. As our ...
Consider a classic expression parser (functors omitted for clarity):constexpr parser p( expr, terms('+', '*', number), nterms(expr), rules( expr(number), expr(expr, '+', expr), expr(expr, '*', expr) ) ); Consider 2 + 2 * 2 input being parsed and a parser in a state ...
