“…Extensive developments have been made in several varieties of meshless methods and applied to many applications in science and engineering. These methods exist under different names, such as: the diffuse element method (DEM) [1], the hp-cloud method [2], Meshless Local PetrovGalerkin (MLPG) method [3,4,5,6,7,8,9,10,11,12], the meshless local boundary integral equation (LBIE) method [13,14], the partition of unity method (PUM) [15], the meshless collocation method based on radial basis functions (RBFs) [16], the smooth particle hydrodynamics (SPH) [17], the reproducing kernel particle method (RKPM) [18], the radial point interpolation method [19] and so on. Inverse problems arise in many heat transfer situations when experimental difficulties are encountered in measuring or producing the appropriate boundary conditions.…”
