一、决策问题的表格表示——损失矩阵 对无观察(No-data)问题 a=δ 可用表格(损失矩阵)替代决策树来描述决策问题的后果(损失):

Definition of search Static search table Dynamic search table Hash table

G( V, E ) where G ::= graph, V = V( G ) ::= finite nonempty set of vertices, and E = E( G ) ::= finite set of edges

A stack is a Last-In-First-Out (LIFO) list, that is, an ordered list in which insertions and deletions are made at the top only. Objects: A finite ordered list with zero or more elements

【Definition】An algorithm is a finite set of instructions that, if followed, accomplishes a particular task. In addition, all algorithms must satisfy the following criteria: (1) Input There are zero or more quantities that are externally supplied

The burgeoning demand for mobile data net￾works has highlighted some constraints on its future growth. Wireless links have always had orders of magnitude less bandwidth than their wireline counterparts. Mobile users have always chafed at this limitation, which essentially forces them to use applications in a manner reminis￾cent of wireline networks of decades past
