帶有期限的作業(yè)排序問題：假定只能在一臺機器上處理n個作業(yè)，每個作業(yè)均可在單位時間內(nèi)完成；又假定每個作業(yè)i都有一個截止期限DI>0(它是整數(shù))，當(dāng)且僅當(dāng)作業(yè)i在它的期限截止以前被完成時，則獲得pi>0的效益。求具有最大效益值的可行解。 文件中包含詳細的源代碼和注釋，以實現(xiàn)這個經(jīng)典的問題。

Embedded computer systems permeate all aspects of our daily lives. Alarm clocks, coffee makers, DIgital watches, cell phones, and automobiles are just a few of the devices that make use of embedded systems. The design and development of such systems is unique, because the design constraints are DIfferent for each system. Essential to the development of an embedded system is an understanDIng of the hardware and software used for development.

his paper provides a tutorial and survey of methods for parameterizing surfaces with a view to applications in geometric modelling and computer graphics. We gather various concepts from DI® erential geometry which are relevant to surface mapping and use them to understand the strengths and weaknesses of the many methods for parameterizing piecewise linear surfaces and their relationship to one another.

簡單的floyd運用 第一行輸入一個整數(shù)C。C是測試的情況（0< C <=30）.第二行一個正整數(shù)N( 0< N <=100),表示道路的總數(shù).緊接N行，每一行包含兩個字符串， Si,，Ti，和一個整數(shù)DI,代表從Si到Ti的距離(0<= DI <=150)。最后一行有兩個字符串，S 和 T，你得找出從S 到 T的最短的距離。地名是不超過120個小寫字符的串（從‘a(chǎn)’到‘z’)。假設(shè)這里最多有100條直接連通兩個地方的路。 Output 輸出包含C行，每一行對一種測試情況。對每一種測試情況，輸出包含一個整數(shù)，假如S 到 T存在一條最短的路,輸出從S到T的最短距離,否則輸出“-1”.
