## Abstract A (plane) 4βregular map __G__ is called __C__βsimple if it arises as a superposition of simple closed curves (tangencies are not allowed); in this case Ο (__G__) is the smallest integer __k__ such that the curves of __G__ can be colored with __k__ colors in such a way that no two curves
For comparison we give below the results of solving the same problem by the method with programmed step control. The initial approximation was the same. In the asymptotically optimal /8/ programmed step control O,=|/l(s+a) , the parameter I must be equal to the least eigenvalue of the Hessian of t
