程序在線評(píng)測(cè)系統(tǒng)
——后臺(tái)評(píng)測(cè)模塊


摘　要：ACM國際大學(xué)生程序設(shè)計(jì)競賽，是一項(xiàng)旨在展示大學(xué)生創(chuàng)新能力、團(tuán)隊(duì)精神和在壓力下編寫程序、分析和解決問題能力的年度競賽。經(jīng)過近30多年的發(fā)展，ACM國際大學(xué)生程序設(shè)計(jì)競賽已經(jīng)發(fā)展成為最具影響力的大學(xué)生計(jì)算機(jī)競賽。隨著其發(fā)展，各高校也越來越重視這項(xiàng)競賽，廣東外語外貿(mào)大學(xué)的程序在線評(píng)測(cè)系統(tǒng)也應(yīng)運(yùn)而生。在這個(gè)平臺(tái)中，用戶只需要提交他們的代碼，系統(tǒng)就可以自動(dòng)地為其程序做出相應(yīng)的評(píng)測(cè)，并且返回相應(yīng)的評(píng)測(cè)結(jié)果。通過這個(gè)平臺(tái)，用戶不但可以鞏固學(xué)科知識(shí)，也可以大大提高代碼的實(shí)踐能力。
后臺(tái)評(píng)測(cè)模塊主要負(fù)責(zé)對(duì)用戶提交的源程序進(jìn)行編譯，運(yùn)行，得到是評(píng)測(cè)結(jié)果再反饋給用戶。

關(guān)鍵詞：在線評(píng)測(cè)，程序設(shè)計(jì)，ACM


Online Judge System
——Background Judge Module

Cheng Jin Yu School of Informatics

Abstract: ACM international collegiate programming contest, is an annual competition that aims at showing their abilitities of innovation, teamwork, programming under pressure, analysing and solving problems. Through more than 30 years’ development, it has become the most influential computing contest for college students and been taken more seriously by many higher eduction universities and colleges, so there comes the Guangdong University of Foreign Studies Online Judge. System which can provide great convenience for programming lovers and students. Users only need to submit their code, then the system can automatically make the appropriate eva luation of its procedures, and returns the corresponding eva luation results. Wiht this platform, users can not only consolidate the academic knowledge, but also can greatly improve the ability of pratical programming.
Background judge module is mainly responsible for a user to submit the source code to compile, run, and return the judge result to the user.
Key words: Online judge, Programming, ACM
