在图形中若于个边(edge)上加上一些值,此数值称为比重( weight ) 。而此图形称为比重图形(Weight Graph ) ,若weight是成本( cost )或距离( distance ) ,则称此图形为网路( Network )。根据Spanning Tree的定义,知一个图形可有许多不同spanning tree ,在network中找出一个具有最小成本( Cost )的Spanning tree ,则此Spanning tree称为最小成本生成树。

利用aiNet执行资源聚类的算法分为两部分:第一部分是aiNet学习算法,如上所述;第二部分是在获得记忆细胞矩阵M和Ab-Ab之间的dij矩阵S基础上,实现连通图的剪枝聚类。 定义 1 无向连通图G:在形态空间Sw上,以M中抗体对应的点为G的顶点,每对抗体之间的亲和力dij为G中两点连接边的权值。 定义2 最小生成树:包含连通图G中所有顶点的一个子图称为G的一棵生成树T。生成树中所用边的权值为生成树的权。权最小的生成树定义为最小生成树(Minimum spanning tree,MST)。

VIP+ is support software for YAMAHA RCX series robot controllers. In addition to the functions of the previously released "VIP Windows" software, VIP+ includes an easy-to-use GUI (graphical user interface). VIP+ also allows control by 2 or more controllers or access to a controller from 2 or more clients via Ethernet connection. ● With VIP+ you can: • Do offline editing of all data used on robot controllers • Operate and monitor robots connected to robot controllers • Do online editing of all data used with robot controllers • Back up and restore robot controller data ● Functions and features newly added to VIP+: • Ethernet connection to controllers • Supports data input in spreadsheet software format • Seamless backup and restoring of controller information such as point data • Syntax coloring • Data transfer between the online controller and an offline document by drag & drop • Executes online commands using a terminal window • Controller tree and document tree functions similar to Windows Explorer

An Arduino core for the ATmega328, ATmega168, ATmega88, ATmega48 and ATmega8, all running a [custom version of Optiboot for increased functionality](#write-to-own-flash). This core requires at least Arduino IDE v1.6.2, where v1.8.5+ is recommended. <br/> **This core gives you two extra IO pins if you're using the internal oscillator!** PB6 and PB7 is mapped to [Arduino pin 20 and 21](#pinout).<br/> If you're into "generic" AVR programming, I'm happy to tell you that all relevant keywords are being highlighted by the IDE through a separate keywords file. Make sure to test the [example files](https://github.com/MCUdude/MiniCore/tree/master/avr/libraries/AVR_examples/examples) (File > Examples > AVR C code examples). Try writing a register name, <i>DDRB</i> for instance, and see for yourself!
