&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Kevin Kelly has written an interesting post about&lt;br /&gt;
the balance of bottom-up processes and top-down control.&lt;br /&gt;
He emphasizes a balanced combination of bottom-up &lt;br /&gt;
contributions and top-down control, and this is in fact&lt;br /&gt;
what you need to engineer self-organizing systems. &lt;br /&gt;
&lt;br /&gt;
The engineering of self-organizing systems is a &lt;br /&gt;
contradiction in itself: how can you organize something &lt;br /&gt;
which organizes itself? If we want to build a &lt;br /&gt;
self-organizing system with autonomous agents, then&lt;br /&gt;
how can we ensure the function ? Agents do by defintion&lt;br /&gt;
what they want. How can you construct a self-organizing &lt;br /&gt;
system?&lt;br /&gt;
&lt;br /&gt;
The answer is: in a balanced, iterative process which &lt;br /&gt;
combines top-down analysis with bottom-up simulation,&lt;br /&gt;
where we step by step define the 'rules of the game'.&lt;br /&gt;
The bottom-up process is needed ensure diversity &lt;br /&gt;
(innovative, random, surprising elements). The&lt;br /&gt;
top-down process ensure unity (e.g. function, quality &lt;br /&gt;
and goal-orientation). Together they form a cyclic &lt;br /&gt;
round-trip process, which can be named synthetic &lt;br /&gt;
microanalysis. This is nothing else but the &lt;br /&gt;
scientific method applied to engineering.&lt;br /&gt;
