Abstract: We examine exponential Diophantine equations of the form $ a{b^x} = c{d^y} + e$. Consider $ a \leq 50$, $ c \leq 50$, $ \vert e\vert\; \leq 1000$, and b and d from the set of primes 2, 3, 5, 7, 11, and 13. Our work proves that no equation with parameters in these ranges can have solutions with $ x > 18$. Our algorithm formalizes and extends a method used by Guy, Lacampagne, and Selfridge in 1987.
