Equal

Description

This operation determines if two transducers have the same states with the same numbering and the same transitions with the same labels and weights in the same order.

Usage

template <class Arc>
bool Equal(const Fst<Arc> &fst1,
           const Fst<Arc> &fst2,
           double delta = kDelta);

fstequal a.fst b.fst

Examples

A	B	C

Equal(A, B);  // returns true
Equal(A, C);  // returns false

$ if fstequal a.fst b.fst; then echo true; else echo false; fi
true
$ if fstequal a.fst c.fst; then echo true; else echo false; fi
false

Complexity

Equal

• Time: linear i.e. O(V₁ + V₂ + E₁ + E₂)
• Space: O(1)
