Abstract
In this research we study a problem of identifying of the right-hand side in a parabolic equation dependent on spatial variables in multidimensional domain. For numerical solution of the set inverse initial-boundary problem we use a conjugate gradient method with purely implicit time approximation. The results of the computational experiment performed on model problems with quasi-real solutions, including those with noise in input data are being discussed.
