Space Game AI c#

Space Game AI c#

im making a small game just to get some practice on AI.
I have enemy objects that fire at the player ship, ive made it so they
follow the player ship and fire randomly but id like to incorporate a
method where if the enemy cant get a clear shot because of another object
in the way then id like it to choose another path to try get a clear shot.
Id really like to use this as a test for some graph searching, Ive looked
at a few algorithms like A*,BFS and DFS but im unsure if this is what I
should be using? or if there is any better ways of doing it?
Regards
