The motion of a flexible string of constant length in E 3 in interaction, corresponding to a variety of physical situations, is considered. It is pointed out that such a system could be studied in terms of the embedding problem in differential geometry, either as a moving helical space curve in E ~
This paper presents two simple approximation algorithms for the shortest 2 2 5 Ε½ . Ε½ . superstring problem with approximation ratios 2 f 2.67 and 2 f 2.596 . The 3 4 2 framework of our improved algorithms is similar to that of previous algorithms in the sense that they construct a superstring by co
