Inverse tasks have been examined of mathematical physics, related to determination of size distributions of including in the matrix-disperse systems, findings of layer complex permittivities of the multi-layered elliptical inclusions, and properties of laminate solids from experi­mental data. In particular, the problems of optical and dialectical spectro­scopy, inverse task of theory of porous media, and also some tasks of radiometry, are exami­ned. In order to solve the indicated class of tasks, a general approach, is used based on minimization of the discrepancy functional between calculated and experimental information. The solution of the min­imization task is built by the method of random search with use of special binary sequences. Graphic and tabular material is resulted, illustrating possibilities of the approach developed.
