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. .
