The novelty of the method is that while increasing the optimization rank of the designed networks, the redundant graph of possible connections between nodes is dynamically reduced. In this case, the redundant graph of the follow-up rank is formed from previous networks rank. The method provides a computer solution to the problem of tracing of large networks containing more than one hundred nodes of the seventh optimality rank. The system is developed for large pipeline networks design of regional and interregional pipe distribution network (PDN) for irrigation purpose.<\/p>\n\n\n\n<p class=\"has-foreground-color has-text-color has-link-color has-lora-font-family has-extra-small-font-size wp-elements-df03325adc83c022634de6b79d43432f wp-block-paragraph\" style=\"line-height:1.4\"><\/p>\n\n\n\n<p class=\"has-foreground-color has-text-color has-link-color has-lora-font-family has-extra-small-font-size wp-elements-bf07b3e643603339d1352f7599ebfe47 wp-block-paragraph\" style=\"line-height:1.4\"><strong><em><strong>Keywords<\/strong>:<\/em><\/strong> pipeline flow network, computer design, tracing, dynamic graph of possible connections of network nodes, dimension reduction, optimality rank increase<\/p>\n\n\n\n<p class=\"has-foreground-color has-text-color has-link-color has-lora-font-family has-extra-small-font-size wp-elements-df03325adc83c022634de6b79d43432f wp-block-paragraph\" style=\"line-height:1.4\"><\/p>\n\n\n\n<p class=\"has-foreground-color has-text-color has-link-color has-lora-font-family wp-elements-2243c08958827295b4bb65835b618630 wp-block-paragraph\" style=\"font-size:12px;line-height:1.4\"><strong><strong>For citation<\/strong>.<\/strong> Abazokov M.B., Kudaev V.Ch.
