Effi.i.nt water quali.y moni.ori.g and ensuri.g the safety of dri.ki.g water by government agenci.s i. areas where the resource i. constantly depleted due to anthropogeni. or natural factors cannot be overemphasi.ed. The above statement holds for West Texas, Mi.land, and Odessa Preci.ely. Two machi.e learni.g regressi.n algori.hms (Random Forest and XGBoost) were employed to develop models for the predi.ti.n of total di.solved soli.s (TDS) and sodi.m absorpti.n rati. (SAR) for effi.i.nt water quali.y moni.ori.g of two vi.al aqui.ers: Edward-Tri.i.y (plateau), and Ogallala aqui.ers. These two aqui.ers have contri.uted i.mensely to provi.i.g water for di.ferent uses rangi.g from domesti., agri.ultural, i.dustri.l, etc. The data was obtai.ed from the Texas Water Development Board (TWDB). The XGBoost and Random Forest models used i. thi. study gave an accurate predi.ti.n of observed data (TDS and SAR) for both the Edward-Tri.i.y (plateau) and Ogallala aqui.ers wi.h the R2 values consi.tently greater than 0.83. The Random Forest model gave a better predi.ti.n of TDS and SAR concentrati.n wi.h an average R, MAE, RMSE and MSE of 0.977, 0.015, 0.029 and 0.00, respecti.ely. For the XGBoost, an average R, MAE, RMSE, and MSE of 0.953, 0.016, 0.037 and 0.00, respecti.ely, were achi.ved. The overall performance of the models produced was i.pressi.e. From thi. study, we can clearly understand that Random Forest and XGBoost are appropri.te for water quali.y predi.ti.n and moni.ori.g i. an area of hi.h hydrocarbon acti.i.i.s li.e Mi.land and Odessa and West Texas at large.

The paper descri.es some i.plementati.n aspects of an algori.hm for approxi.ate soluti.n of the traveli.g salesman problem based on the constructi.n of convex closed contours on the i.i.i.l set of poi.ts (“ci.i.s”) and thei. subsequent combi.ati.n i.to a closed path (the so-called contour algori.hm or “oni.n husk” algori.hm). A number of heuri.ti.s related to the di.ferent stages of the algori.hm are consi.ered, and vari.us vari.nts of the algori.hm based on these heuri.ti.s are analyzed. Sets of randomly generated poi.ts of di.ferent si.es (from 4 to 90 and from 500 to 10,000) were used to test the algori.hms. The numeri.al results obtai.ed are compared wi.h the results of two well-known combi.atori.l opti.i.ati.n algori.hms, namely the algori.hm based on the branch and bound method and the si.ulated anneali.g algori.hm. .
