Maximal Independent Set and Minimal Vertex Cover. Maximal Independent Set and Minimal Vertex Cover.
I can have multiple maximal independent sets for a graph..
Now for a particular Maximal independent set , if I remove the vertices contained in it from total vertices in a graph...then my question is am I sure to get a minimal vertex cover...?
Like say if the vertices of a graph are "abcde" and say if "abc" is a maximal independent set  then can I say for sure that "de" is a minimal vertex cover...?
Plz correct me if I have done something totally wrong or is the claim given wrong...by seeing this.

Yes, they will be a minimal vertex cover.
First, the fact that $S$ is an independent set (not necessary maximal) means that no edge lies within $S$, so every edge meets $V\setminus S$, meaning that $V\setminus S$ is a vertex cover.
Secondly, the fact that $S$ is a maximal independent set means that for every vertex $v\in V\setminus S$, adding $v$ to $S$ does not give an independent set. Thus there is an edge meeting $v$ and some vertex in $S$. If we removed $v$ from $V\setminus S$, this edge wouldn't be covered, so we would no longer have a vertex cover. This is true for every $v\in V\setminus S$, so $V\setminus S$ is minimal.
