  We give a calculation scheme for the cosmological constant computation with
the help of the Wheeler-DeWitt equation. This last one is regarded as a
Sturm-Liouville problem with the cosmological constant considered as the
associated eigenvalue. By fixing the ideas on a
Friedmann-Lema\^{\i}tre-Robertson-Walker line element in ordinary gravity, we
apply this calculation scheme on distorted gravity. By distorted gravity, we
mean all the deviations from General Relativity. We restrict our proposal on
Gravity's Rainbow and Noncommutative geometry. A brief comment on
Ho\v{r}ava-Lifshitz (HL) theory is discussed.
