 Every optimization problem can be written in matrix form. For some problems, it may seems trivial, but it's coherent and easy to understand. Secondly, when it comes to algorithms to solve them, it's more explicit in matrix form. Thirdly, the abstraction algorithm for problem modeling helps a lot in understanding.
 
-## 1,  What? and Why?
+## Introduction
 
-The MILP can be formulated in the following matrixes:
+The MILP can always be formulated in the following matrixes:
 
 ```
-min  vecFf' * vecXx + vecGg' * vecYy
-s.t. matAa1 * vecXx + matCc1 * vecYy <= vecBb1
-     matAa2 * vecXx + matCc2 * vecYy <= vecBb2
-     vecXx in R
-     vecYy in Z+
+min  vec_c' * vec_x + vec_f' * vec_y
+s.t. mat_aCap * vec_x + mat_bCap * vec_y <= vec_b
+     vec_x in R
+     vec_y in Z
 ```
 
 There are two directions for matrix optimization to develop: make modeling easier and solving faster.
 
-### 1.1,  Specialization
+In this package, there are formulated algorithm for four kinds of optimization problems, and two decomposition algorithms for faster MILP solving.
