无路

Given a ring and a set of communication requests. Each request is represented by a pair of nodes, and associated with a profit. To satisfy a request in the undirected ring, we need to determine a path between the two nodes of the request in the ring. To satisfy a request in the directed ring, we need to determine a directed path from the source to the destination of the request in the directed ring. The goal of the call admission control problem is to determine and satisfy a maximum profit subset of the requests such that for every edge of the ring, the number of satisfied requests that are routed through the edge does not exceed the capacity of the edge.

要在无向环中实现一个呼叫，需在环中指定该请求所对应的两个顶点之间的一条路，要在有向环中实现一个呼叫，需在环中指定该请求的源节点到目的节点的一条路，环网络呼叫接纳控制问题的目标是确定最大利润的呼叫子集，在环中实现该子集中的每一个呼叫，使得经过每一边的呼叫的数目不超过该边的容量，对于无向和有向环网络呼叫接纳控制问题，我们均首次给出了多项式时间近似方案。

The battle once begun, its very various changes,--the resistance of Hougomont; the tenacity of La Haie-Sainte; the killing of Bauduin; the disabling of Foy; the unexpected wall against which Soye's brigade was shattered; Guilleminot's fatal heedlessness when he had neither petard nor powder sacks; the miring of the batteries; the fifteen unescorted pieces overwhelmed in a hollow way by Uxbridge; the small effect of the bombs falling in the English lines, and there embedding themselves in the rain-soaked soil, and only succeeding in producing volcanoes of mud, so that the canister was turned into a splash; the uselessness of Pire's demonstration on Braine-l'Alleud; all that cavalry, fifteen squadrons, almost exterminated; the right wing of the English badly alarmed, the left wing badly cut into; Ney's strange mistake in massing, instead of echelonning the four divisions of the first corps; men delivered over to grape-shot, arranged in ranks twenty-seven deep and with a frontage of two hundred; the frightful holes made in these masses by the cannon-balls; attacking columns disorganized; the side-battery suddenly unmasked on their flank; Bourgeois, Donzelot, and Durutte compromised; Quiot repulsed; Lieutenant Vieux, that Hercules graduated at the Polytechnic School, wounded at the moment when he was beating in with an axe the door of La Haie-Sainte under the downright fire of the English barricade which barred the angle of the road from Genappe to Brussels; Marcognet's division caught between the infantry and the cavalry, shot down at the very muzzle of the guns amid the grain by Best and Pack, put to the sword by Ponsonby; his battery of seven pieces spiked; the Prince of Saxe-Weimar holding and guarding, in spite of the Comte d'Erlon, both Frischemont and Smohain; the flag of the 105th taken, the flag of the 45th captured; that black Prussian hussar stopped by runners of the flying column of three hundred light cavalry on the scout between Wavre and Plancenoit; the alarming things that had been said by prisoners; Grouchy's delay; fifteen hundred men killed in the orchard of Hougomont in less than an hour; eighteen hundred men overthrown in a still shorter time about La Haie-Sainte,--all these stormy incidents passing like the clouds of battle before Napoleon, had hardly troubled his gaze and had not overshadowed that face of imperial certainty.

交锋以后，战争的非常复杂惊险的变化，乌古蒙的阻力，圣拉埃的顽抗，博丹的阵亡，富瓦战斗能力的丧失，使索亚旅部受到创伤的那道意外的墙，无弹无药的吉埃米诺的那种见死不退的顽强，炮队的陷入泥淖，被阿克斯布里吉击溃在一条凹路里的那十五尊无人护卫的炮，炸弹落入英军防线效果不大，土被雨水浸透了，炸弹陷入，只能喷出一些泥土，以致开花弹全变成了烂泥泡，比雷在布兰拉勒出击无功，十五营骑兵几乎全部覆没，英军右翼应战的镇静，左翼防守的周密，内伊不把第一军的四师人散开，反把他们聚拢的那种奇怪的误会，每排二百人，前后连接二十七排，许多那样的队形齐头并进去和开花弹对抗，炮弹对那些密集队伍的骇人的射击，失去连络的先锋队，从侧面进攻的炮队突然受到拦腰的袭击，布尔热瓦、东泽洛和迪吕特被围困，吉奥被击退，来自综合工科学校的大力士维安中尉，冒着英军防守热纳普到布鲁塞尔那条路转角处的炮火，在抡起板斧去砍圣拉埃大门时受了伤，马科涅师被困在步兵和骑兵的夹击中，在麦田里受到了贝司特和派克的劈面射击和庞森比的砍斫，他炮队的七尊炮的火眼全被钉塞，戴尔隆伯爵夺不下萨克森－魏玛亲王防守的弗里谢蒙和斯莫安，第一○五联队的军旗被夺，第四十五联队的军旗被夺，那个普鲁士黑轻骑军士被三百名在瓦弗和普朗尚努瓦一带策应的狙击队所获，那俘虏所说的种种悚听的危言，格鲁希的迟迟不来，一下便倒在圣拉埃周围的那一千八百人，比在乌古蒙果园中不到一个钟头便被杀尽的那一千五百人死得更快，凡此种种迅雷疾风似的意外，有如阵阵战云，在拿破仑的眼前掠过，几乎不曾扰乱他的视线，他那副极度自信的龙颜，绝不因这些变幻而稍露忧色。

Chorus oh, you never turned around to see the frowns on the jumpers and the clowns when they did their tricks for you you never understood that it ain't no good you shouldn't let other people get your kicks for you you used to ride on your chrome horse with your diplomat who carried on his shoulder a siamese cat ain't it hard when you discovered that he really wasn't where it's at after he took from you everything he could steal princess on a steeple and all the pretty people they're all drinking, thinking that they've got it made exchanging all precious gifts you better take your diamond ring, you better pawn it babe you used to be so amused at napoleon in rags and the language that he used go to him he calls you, you can't refuse when you ain't got nothing, you got nothing to loose you're invisible now, you've got not secret to conceal Like A Rolling Stone

没了回家的方向、也没人认识像个流浪汉高傲的王子，和所有那些漂亮的人们他们都喝着酒，琢磨着怎么能淘换到更值钱的玩意儿但是你呢，你得把你的钻戒举起来，把它当了人都有倒霉的时候，看着戏里走背字儿的拿破仑你不是曾经还挺得意吗？现在轮到你了，拿破仑在招呼你了，你无路可退了当你一无所有的时候，你不用担心会失去什么了现在你已经透明了，已经没啥可隐瞒的了孤身一人的滋味你觉得怎么样？没了回家的方向、也没人认识像个流浪汉。

The split between the two groups can hardly be papered over.
