This paper presents optimization models for a fault tolerant software by selecting a set of versions for a given program. The objective is to maximize the reliability of the software satisfying a budget limitation. Optimization models are developed for two block recovery schemes: (1) independent recovery block and (2) consensus recovery block. The paper also presents simple formulas to calculate the reliability of the two schemes.
