“…Where the development of the numerical method was strongly affected and this progress is still being seen constantly. Inverse problems in phoneme setting have been examined by many authors such Radial Basis Functions method and Fragile Points Method applied in [10] and [33] respectively, Tikhonov regularization method used in [14], [29], [6], [13], [20], [2], [16] and Lavrentiev regularization method [21]. The twentieth century is constantly being researched for practical applications, such as in medicine, biology geophysics mineral investigation, filtration and computer tomography [12], [24], [31].…”
