Yes, they will, depending. If you give them the attack order they will seek an alternate route to intercept the ship if the warp point closes. And if a new warp point opens that is a mor direfct route they will use that. However if the order you gave was to warp and that warp point is closed they will stop, unless you chain additional orders.

Warp opening and closing happens at the begining of the turn. A warp point between two systems can be opened on teh same turn as one is closed between those same two systems as long as the one is closed first. This will happen if the empire closing the warp point is higher on teh player list then the empire opening the new one. For one empire trying to do both it's a little trickier cause you have to make sure your closing ship closes the warp point before the opening ship opens it. There may be ways to do that. I can't guarantee they will work though.
