While Lee Wei and Ying Yin is preparing themselves for the MIT GAMBIT interview, I was looking at what is happening the Gaming World. Well it is interesting to found a subject for College Students that is about playing Games instead of Creating Games.



Students in UC - Berkeley can take up StarCraft studies for college credits.

One of the line that I am quite interested for the course is "Calculus and Differential Equations are highly recommended for full understanding of the course." I think it is mainly on to the - flanking maneuver.

Well, here is what I pickup from the course web site
Week 3 Question 1.
A Terran Siege Tank in Siege Mode attacks for 70 damage, has 150 hp, and 1 armor. This
means that after two upgrades, a Siege Tank can kill another Siege Tank in two hits
instead of three. What are other significant damage combos? Be sure to investigate not
just upgrades and numbers of hits, but also unit group combinations. Which numbers are
worth noting?

Week 3 Question 3.
Is it more advantageous to attack in a line or to envelop your opponent’s army? Prove your point using flux calculations.

I wonder what is the answers to that kind of questions?
