min f(x)　{x | g(x) <= 0 ,h(x) = 0}

What does this system make you inspired? We've often faced with systems based on this formula in real. In present days,the size of these system is getting larger and larger. In order to break through this situation, We develope some good algorithms to find a local minimum efficiently and implement them the computer with paralell architecture . Maybe our trials make our world happy.
