“…A few theoretical articles concern conditional stability and the data compatibility of the solution notably in [1,3,8,[12][13][14][15]. As yet, there are many published works in this field based in several numerical methods, such as the Lie-group shooting method (LGSM) [5], the coupled method [16], the fundamental solutions method [6,17], the meshless method [7,18], the genetic algorithm [4], and the conjugate gradient method (CGM) [19][20][21]. In [22,23], these numerical methods were considered to solve two and three-dimensional inverse transient heat source problems.…”
