Vaziranis are basically Hindu-Sindhis and worship Lord Jhulelal, an Avatar born according to divine message depicted to humans through Bhagvad Gita to protect Hindu-Sindhis.
Jerrum, Valiant, and Vazirani showed that every #P-complete problem either has an FPRAS, or is essentially impossible to approximate; if there is any polynomial-time algorithm which consistently produces an approximation of a #P-complete problem which is within a polynomial ratio in the size of the input of the exact answer, then that algorithm can be used to construct an FPRAS.
