CPS_Alexander (v4.9.1)

Author File Description
File Details
Version: The Conquerors 1.0c
CPS_Alexander is a Random Map AI that plays with any civilization on any kind of map except islands. On mixed maps it builds a small fleet to defend its shoreline and to harass enemy fishing ships. It doesn't build transport ships and navy is not the core of its army, thus it will not play on islands.
All supported settings are described below.

Game Type: Random Map
Location: Any map that doesn't require transport ships to carry soldiers.
Map Size: Any
Teams: Any combination
Resources: Standard (Low)
Difficulty: Hard recommended
Population: 175 or 200 (200 recommended)
Starting Age: Dark Age
Victory: Any (conquest recommended - this AI does not build Wonders)
Civilization: Any

This AI plays 10 different strategies and several their variations (every civ can pick from at least 3 strategies).
It can flush, or go Fast Castle.

Note: This AI does not cheat (except on Hardest mode, when it gets additional
resources as any other AI does. It uses cc-commands only to count tress
and stone or gold piles). If you think that you need more challenge, use
version H (has some cheats) or S (cheats extremly) - both included in zip file.

twaytwya how do you download this? do i unzip and place in AOK directory? i don't even know how to do that! sorry i am new to this...all i see is a lot of .per and .ai files. i don't know how to download those. i don't know how to unzip that and how to place it in the right directory/file...thanks for your help!

To install this AI just unzip all files to Microsoft Games\Age of Empires II\AI directory.
twaytwya when u say unzip all files to AI directory do u mean replace the existing AI directory file with this new one? and how do u unzip a file to a particular directory?
TheLaughingMule Unzip the zip file. Put the files (.ai and .per) into the AI folder in your game.

marathon I liked it :)
Reliable, it seems that it can handle weird situations, like far forests, or limited space for buildings.
It trains good armies, its eco is strong.

It doesn't fight that well (v.4.7.4), but it can easily be improved in the future.

Well done, Suriel! I really like all-civ scripts. Yours plays all kinds of land maps, including nomad, and you have worked hard on it. There are some good scripting ideas in it, too.
File Author
I'm glad you enjoyed it :)

I'll be updating the script when I have some free time and fresh ideas.

Any suggestions what to improve are appreciated.
marathon I would like to give feedback, but for now I am studying it, mainly searching for ideas to use. It has some ideas that I am only now in the process of adding into my own script. My ai wins against yours, but it plays only Byz, and only 1 strategy. I initially wanted to make it just like yours and Chameleon, and I will, in time.

Your ai is pretty solid, with a variety of strategies. It loses against strong scripts, but not without a good fight. Well done, even if it isn't your first script. Thanks to its good structure it can be easily improved dramatically.

One thing: since you've studied The Horde, look at it a little deeper: it's not only the target-evaluation numbers that help in battle: sentry-distance, enemy-sighted-response-distance and other things also are critical. Also, it seems to me that those evaluation numbers are better for fast armies.

Come at aiscripters for a more detailed feedback by me, when I have tested it more. People there are all very friendly and we help one another all the time.

And, welcome to the Ladder :) Don't care for any defeats that you will get (later, you will win the first couple of games), it's all about fun.

About 2 years ago I had an account on aiscripters (I've got much information from that
site in the past and many useful files like tournament packs with some old good scripts).
But because I stopped scripting for a while, I haven't log to it for over a year. And it
seems that the account ceased to exist. I created new one, about a year ago, but it has never been activated.

I created another one several minutes ago. I hope this time I won't have to wait forever for activation ;)

About The Horde: I just started examining it, so right now I don't know it very well.
But I'll definitely spent more to time to look deeper into it. This script is awsome :D
I especially like the way it decides when to flush. I'm currently working on something
similar (the code is now at very early stage) because my AI seems to work better when
can FC, so I would like it to flush only when it's necessary.

About my script: Its structure is an effect of many changes I applied to it through time.
At some point I just decided I don't want to rewrite the whole code over and over again so I made it as modular as possible. It's (structure) still not perfect (many changes resulted in some problems that cause sometimes big mess :P) but it helps a lot.

About the Ladder: Fun is the reason I joined it :D

marathon Your structure is good. Since I am scripting for only a few months, I am impressed by its versatility. I take my hat off to it.

Many, many strategies. Of course, many of them are not optimized, but that is natural. I have to admit that that it masses a strong army quickly with Mayans and that it has good dark-feudal ages. But its castle-age needs some balancing for many civs/strats, especially the booming. And, the only real weakness I observed has to do with dropsites: they are too close to enemy, probably a result of a too low sn-minimum-dropsite-buffer and huge camp-distances.

I am often testing against it, and I will collect more info, resulting in suggestions for individual strategies. But your Mayan play is good, top. My script can't beat them, and often loses against other civs/strategies.

Your code seems to flush well, but it actually has some problems with FC, when it has to produce food for both booming and army/upgrades. As for the flush detection, I too copied The Horde's simple method. The result was awesome.
File Author
One thing. Among these strategies there are 18 civ specific strategies. I'm no longer upgrading them and they are rarely used (1 to 2% chance to be used in a game). You may just ignore them.

As for dropsites you are right. I just ignored this strategic number because I know that wrong value may sometimes block placing camps at all. Just didn't know what value will be ok so I just left it as it is.

Most strategies used by Mayans were tested and optimised for Aztecs (except the one that trains lots of xbows). So if you think they work good for them you should expect a bit better performance with Aztecs :)
In general all those strategies are used by many civs but had been optimised only for one. For example knight based strategies have been tested and optimised for Huns (for which they work best but surprisingly they work equally good for Teutons although I haven't added any optimisation for them).
