WebNov 21, 2015 · $\begingroup$ I think this solution is the projection of the cross product of two NFAs. One is the actual NFA accepting L. Another one is the reverse NFA i.e. the NFA of L with arrows in the opposite direction, along with a new state which acts as the starting state and such that you can reach any state in F just by the empty string. WebDeterministic Finite Automata [2/2] A string x ∈ Σ * is accepted by M if ˆ δ (s, x) ∈ F and is rejected by M if ˆ δ (s, x) 6∈ F. The set or language accepted by M , written L ( M ), is the …

Following this transition causes c c to be pushed onto the stack. Any of the 3 symbols a,b,c a,b,c can be \epsilon ϵ. hyperbolic vs sigmoidal curve
