AI Improvement Idea

I'd like to work with Formuals and functions in Formula Ai, improve them and add new functions for simplyfying modularity and general use.I want to create a debugger GUI for testing and debug purpose of formulas. This gui will include candidate move which is executing now and u can see which line is parsing/executing and you have a options to wait in one line or go to next line like C++ debuggers in many IDEs.And i also want to make primitive library for FAI and thinking of adding some new candidate move types for improve deciding state.I think move and attack is too limited types and choosing one of them might be ignore other type but choosing other can be gooder then this one so we need decision type for move or attack etc.Or we can improve candidate move semantic&syntax to decide: type: evaluation: attack: then what if decide says ai will choose type (movement or attack) .

'Adding Global Functions and variables to Formula AI and Improvement Formulas'

Loop structure Idea:

'while' function:I think most important requirement for Formula language is loop structures,adding the loop structures will allow run one or more lines of code repetitively.Loops will decrease complexity of codes.And we have a chance to trace all items in lists and add conditional to them.Function syntax will looklike that

while(i=0)(<assignment>,if(' found ',i = 1,0))

Selection Idea:

'specific_choose' function:Specific choose function will allow to choose specific items(unlike choose not highest).Function syntax will look like that <result> = choose(<inputl list >,<number>,[<string>,]<formula>) its like choose function but we can choose order of item.

Squad Division Idea:

'squad_leader' attribute: I want to implement squad_leader attribute to all variables then we can check if unit is squad_leader choose by AI.(squad_leader can have two value 1 or 0)

'squad_number' attribute: This attribute will determine units squad number.Every unit will belong one squad and they have number for controlling squads every turn in breaking squad formula.

'squad_empty_slot' attribute: This attribute will contain value which is how many unit needed in squad.In squad idea Ai will divide units to squads -4 people squads- for example if ai side have only 3 men or 13 man maybe ai will break squads but write squad_empty_slot to 1-2,3- then if we recruit unit ai will check squads if squad_empty_slot 's value != 0 and if any squads found ai will add unit to this squad if ai cant find any squad which is have empty slot ai will give unit to squad_leader promotion and refer squad_empty_slot to 3.

'breaking squad.fai' formula: This formula will be called in every formula_ai turn.Formula will look unit's squad numbers.If a unit that hasnt got any squad Formula will look like squad_empty_slot[last_number_of_squad] if slot any empty slot there unit will be added this squad. If not formula will create new squad and give him squad_leader promotion.Also there can be some improvements like optimization of squad_leaders etc.


Follower Idea(Strategy):

I will implement a formula for squad following.This formula will get empty adjacent_locs (we can take hexes in his back which is distance_between(1 or 2 of them ) of leader and move near or back of his squad leader. If leader will attack some unit every unit in his squad will attack if they have enough movement point if not they will go his near or back again.(Also we can push queue structure to their movements and pop them but there is no need for that i think.)

Recruitment idea:

'unit_price' attribute: this function will return how many gold we need for recruit unit.

'available_recruits' function: This function will return list of units which we can recruit in current turn.

'will_available_recruits' function: This function will return list of units which we can recruit if we wait one turn.Function will calculate how many gold will we have in following turn and looks units prices.

'strong_enough' function: This function will return can we live one more turn.In this function we will look how many unit we got and their levels etc. and also we will look enemy_unit attributes so this function will turn 1 or 0 about we can live or not.

Recruitment Strategy: In recruitment state we will look if the leader staying at keep.If not, we will look if leader can reach keep in this turn.So if leader cant reach keep, ai will pass recruitment state. But if leader is staying in keep or can reach castle(this method will return true) ai will call available_recruits function for learn info about which units we can buy. After that ai call will_available_recruits method which includes if we will wait one turn which units will be available for recruit.At last we will call strong_enough function for look can we live one more turn.So ai will decide to wait or recruit immediately.With this strategy we can have gooder units and we can spend our money to gooder units.

ps:i will add new functions and new formula ideas to this area about making attack strategy soon...

Patches

[Patch 1138]-I've implemented one of Formula AI improvements suggestions on the EasyCoding page-poisoning imrovement- and i wrote a scenario to test my improvement,under the guidance of boucman and with help of Dragonking.

[Patch 1145]-I've implemented one of Formula AI improvements suggestions on the Easy Coding page-healing improvement-

[Patch 1143]-I've implemented a new global function named distance_list_between which is allow us to take a list between one specific unit location and other specific -or all- units.But right after i finished this function boucman explained we can already take a list with for example map(my_units,distance_between(me.loc,loc))But submitted cause i think it might be worthy for general usage.

[Patch 1142]-I've implemented a new global function named Encapsulate which is comparing two list and return 1 if list1's all elements is also list2's elements.And return -1 if list1's all elements are not in list2.

Basics And Other Questions

Informal Introduction:

I am interested in GsoC and especially Wesnoth to improve my skills about Game Developing and also Open Source Developing.At the same time while improving myself i want to add somethings to game from myself and evolve this great game.

Experience:

I am at the end of third of four year bachelor education in Computer Engineering. After these years i became experienced about some computer languages(C,C++,Java,Perl,Python,C#,SQL etc.). And i experienced both procedural design and Object Oriented Design(including UML Design).I'm in advanced level in both C C++ and Java languages.I'm also the chief of the game development group in my school. I have developed many projects for School and a little for some companies. When i was intern -last summer- i had developed a Flight Simulation for Defence Industry. I worked on Linux(ubuntu) to develop,i used C++,Open Gl and Sdl libraries,image generators (MPV,CIGI).I developed whole simulation myself with help of my intern mentor. About teamworking the most crowded project that I have ever worked, included four people. If I get acception to this project, this will be my first time working with GSoC and the biggest open source project that i have ever worked on.

I'm a passionate gamer.My game genres of choices are Fantasy Role Playing games,MMORPGs,Real time Strategies,Simulations and Adventures. I'm playing Computer and Console games since i was 8 years old. First game that i played is Prehistoric. My priorities in games are about storyline and theme, not the graphics. So i believe that new generation games have huge problems about that.I'm playing Wesnoth about 2 week and i really enjoyed it reminded me Heroes III but Wesnoth's content is more flexible than Heroes and have gooder Theme. Game is harder then most turn based games and need to create good strategy for the win.

Communication skills:

My primary spoken/written language is Turkish.So english is my second language. But I have no problems interacting with others in a professional or social contacts.I could give and also receive constructive advices.

Project:

From the project ideas that I saw,I thought what I would like to participate in most will be "Write a primitive library for Formula AI". Im not too familiar with AI developing but its is in my interests. I'm trying to be familiar with formula AI about 1.5 week -playing game , looking to header files and class reference , read documentations about FAI on wiki , looking for forum threads etc. - So I choose this project because i know c++ well and i have also some real life experience on c++.Also i think i can learn quickly how AI is processing and i can develop new primitive library to AI.

About timeline; Generally my school ending at 2 p.m(GMT) and im usually awake to 12-1 a.m(GMT).At fridays my school ending at 10 a.m so i'm empty whole day after 10 a.m these days and off course i'm empty all weekends.(Turkey using GMT +2 btw).But i can both work and develop or research when i'm at school.Although i have exams at starting 25May and finishing at 7 June(And my school is ending at this day too). So in this two weeks i may not be doing much.On summer i have a internship but it will end at 4 p.m everyday(except Weekends-On weekends i can research and develop all day) and i can awake those days to 12-1 a.m too. So i can work much these hours(after 4.pm) and i can be online generally at 4 p.m on summer(at June-July).But i can develop when im at work(= before 4.pm) however it may not too much.And would have no problem for me to talking over the phone, internet or otherwise.

I wish to participate in the Google Summer of Code and especially Wesnoth because i want to be a Game Developer and Summer of Code is my chance to do that.I'm trying to improve myself but i need a mentor and i need to do something that is worthy.In Turkey, Game Development is really weak issue so finding a good mentor and good community is really hard.And also i want to take place as a Open Source Developer cause my philosophy about Softwares correspond with Open Source philosophy. I believe that knowledge and information would be free, I want to stay as developer in Wesnoth after GSoC. So im looking to GSoC as chance to boost myself and the door to being in developer team in Wesnoth.

Practical considerations:

I am using Subversion(svn).I'm good at C++ and writing about 2.5 years with C++ and i know Python about a year.And i'm using environments (eg cmake/autotools/scons) about 2 year. I am normally use Java and Python for development cause this languages have really good readability,reliability also they have good support for abstraction although they are really strong in their roles.And off course they are Open Source!!. I am using eclipse and qt4 in Linux(for java). When i'm writing c++ or python code on linux i generally use vim editor. On windows i'm using both visual studio and eclipse for developing.

Experienced Languages: C,C++,Java,Python,C#,Perl,PhP,Mysql,Javascript,Html,Xml,Action Script 3,(Cinema 4d this is not language but i used for design some 3d objects)
