Definition 4 (bad reversal) A bad reversal is a reversal that creates a bad component.
Theorem 1 For a permutation without a bad component, there is an O(n) algorithm for listing all sorting reversals.
Proof By definition, there exists at least one reversal that creates a bad component from an ominous substring.
We first characterize what we call ominous substrings of the permutation, those substrings that could be turned into a bad component with one reversal.
Proof The probability of seeing a bad component in a permutation taken uniformly at random from the set of all signed permutations is O n-2) [ 15].
Definition 3 (bad component [ 16]) A bad component of a permutation is a component with at least 4 elements, where the sign of every element is the same.

Our algorithm searches for ominous substrings by doing the following: for each element of the permutation we posit that it is a smallest element of a potential (after a reversal) bad component and continue by scanning the permutation to detect an ominous substring.
The ROC curve generated by a Bayesian classifier ('Learn Good From Bad' component) in the 80% - 20% stratified partition validation is shown in (A).
Science
Known algorithms that list all sorting reversals check, one by one, if each of the potentially Ω(n) cycle-splitting reversals is unsafe by applying the reversal and then running a linear time check as to whether it produced a bad (unoriented) component [ 9, 10].
If ρ includes both e and f, this implies that the bad component already exists in π, which is a contradiction.
Since it is unsafe, the permutation π ○ ρ has at least one bad component created by ρ.
Expert writing Tips
Best practice
When describing technical issues, be specific about which "a bad component" is causing the problem. Providing details helps in troubleshooting and understanding the failure.
Common error
Do not simply state that there is "a bad component" without specifying its function or location within the system. This lacks actionable information and can confuse the reader.
