The intermittency behavior of emitted particles produced in heavy ion collisions has been studied using both default and string melting modes of A Multi-Phase Transport (AMPT) model-generated data. In this article, the Scaled Factorial Moment (SFM) technique has been adopted to study the intermittency. The goal of the study is to search for critical points of strongly interacting matter. It is the region of QCD phase diagram where the properties of strongly interacting matter exhibit non-analytic behavior. Finding the exact location is citical point is one of the prime objectives to study fluctuation via SFM analysis. There are enormous number of results that have been published by the STAR, NA61/SHINE, NA49 collaborations for different collision systems. At SIS100 energies of FAIR, it is expected that the QCD phase diagram exhibits a first-order phase transition between hadronic matter and partonic matter at high net-baryon densities and moderate temperatures. So, it is also important to study such observables at lower energy too. The intermittency analysis is performed in 2D (
) space for AMPT-generated data for Au+Au collisions at 
10 AGeV beam energy. It is also checked the existence of intermittency in the generated data by manipulating the Lund String Fragmentation parameter, b.
