whenever i build a worker,i always automate it to improve the surroundings...is it a good way to use this method automate?or DIY?
If you don't care about worker efficiency and want to concentrate on the other parts of CIV4, then worker automation is ok. However, terrain improvement is one of the most important parts of the civilisation series and it got even more important in CIV4, so it will make a serious difference to the development of your civilisation if it is done efficiently. The AI will of course perform with limitid efficiency as it has a limited level of 'pre-programmed intelligence'.
Things the human player can do better:
1) Focus on the tiles that need to be improved first,
2) Choose a better distribution of the different tile improvements: the right amount of farms, cottages, workshops, etc. ,
3) Create specialist cities (cities that are good at one thing to the exclusion of other elements) like:
-cities that focus on food for specialists,
-cities that focus on hammers for wonders or military units,
-cities that focus on commerce for research and gold,
4) Protect the workers from enemies (it's fairly easy to capture AI workers),
5) Look into the future and determine the future optimal distribution of the various improvements for this city.
