On an algorithm to decide whether a free group is a free factor of another
We revisit the problem of deciding whether a finitely generated subgroup H is a free factor of a given free group F . Known algorithms solve this problem in time polynomial in the sum of the lengths of the generators of H and exponential in the rank of F . We show that the latter dependency can be made exponential in the rank difference rank(F )− rank(H), which often makes a significant change....
متن کاملHow to decide whether small samples comply with an equidistribution.
The decision whether a measured distribution complies with an equidistribution is a central element of many biostatistical methods. High throughput differential expression measurements, for instance, necessitate to judge possible over-representation of genes. The reliability of this judgement, however, is strongly affected when rarely expressed genes are pooled. We propose a method that can be ...
متن کاملAn improved algorithm to reconstruct a binary tree from its inorder and postorder traversals
It is well-known that, given inorder traversal along with one of the preorder or postorder traversals of a binary tree, the tree can be determined uniquely. Several algorithms have been proposed to reconstruct a binary tree from its inorder and preorder traversals. There is one study to reconstruct a binary tree from its inorder and postorder traversals, and this algorithm takes running time of...

متن کاملHow to decide whether to buy new medical equipment.
in primary care medicine, deciding how to invest a practice’s precious capital resources is becoming more difficult. Purchasing procedural medical equipment is something many physicians may consider, and sales representatives for the equipment can always make the investment sound enticing. But how do you really know if the investment will be beneficial to you – financially or otherwise? Wheth...
