关于raw的好处http://www.catinfo.org/?link=makingcatfood。

1，完全自己买原料来做。好处是可以自己控制配方，特别是对一些肠胃敏感的猫，可
以避开过敏的食物。自己做要保证配方均衡，一定比例的肉，骨和内脏，还要注意食物
卫生安全。你需要一个绞肉机，至少要能绞比较软的鸡骨头。这种绞肉机都比较贵，不

2，肉和内脏自己买，钙还有其他的用买的supplement。这样的话不用绞骨头，省点事
，买个便宜的绞肉机就可以了。如果对添加钙，或其它维生素有疑惧，我觉的可以用
primal的冷冻的raw supplement，去他家网战看成份，主要是绞好的骨头和内脏。

我不是高手,但是做N-dimensional assignment一段时间了,下面
写的是一些已知的结果:
你的问题是一个2-D assignment问题,可以relax integer constraints,
用LP求解,最好是用primal-dual interior point method.
如果是sparse问题,modified auction可以很快得到结果,如果是dense

分别用auction和JVC解相应的子问题.如果你知道其中一些约束,问题是能
不能转化为linear cost flow问题,如果可以,则偶推荐用auction求解.不
能的话对提高运算速度从worst case角度看无帮助.
对3-D以上assignment问题,通常搜索最优解是NP hard,此时不能relax integer
constraints,但是可以解dual problem using successive Lagrangian relaxation.

附属公司与不同的独立第三方订立协议，出售集团在粮油、乳制品及矿泉水业务中的全
部权益，总代价约为人民币27亿元。出售事项完成后，恒大集团将不再持有粮油、乳制
品及矿泉水业务的任何权益。公告解释称，这是基于公司的战略考虑，使自己能更加专
注于房地产及其他相关业务。
恒大集团在公告中称，由于有关出售事项的适用百分比率均低过5%，出售事项不须遵守
上市规则第14章的规定。出售事项之财务影响按照适用会计准则，根据粮油集团公司、
乳业集团公司及矿泉水集团公司于2016年8月31日之未经审核净负债约为人民币33亿元
，及出售该等业务的总代价人民币27亿元，本公司预期将自出售事项确认除税前未经审

然而这些手段，和今天要介绍的这个女子团体相比，完全就是小儿科。
自我拍卖、全裸MV、被粉丝扇耳光……在台上“无恶不作”、没有尺度。她们是“偶像”这一观念的破坏者，也曾被媒体评价为史上最最“重口味”的女团。
BiS
她们曾以单曲《My Ixxx》出道。在MV里，成员们身着肉色乳胶服装做出全裸装扮，视频在Youtube上被观看了上百万次。从此以后，色情和暴力的大门彻底向粉丝们敞开了。
暴力、援交、抽烟、扮演蟑螂，所有和女子偶像不符的行为她们都玩儿了个遍。
在歌曲《STUPiG》中扮演“机械僵尸”。
在第三首单曲《primal.》的MV里，让镜头跟随胃镜拍摄自己的口腔深处。
当然，这还只是MV而已。演唱会中的BiS比这还要疯狂一万倍。
在演出时，成员们会突然“跳水”，在男粉丝的托举中“滚”遍全场。就算露出胖次、被抓胸部也毫不在乎。
表演到极度疲惫或情绪高涨时还会拿电击棒冲到台下疯狂电粉丝，或者拿吉他砸粉丝。
