- Points of improvement in Stratego programming(PDF)
This is a first attempt to define a theoretical framework for game knowledge in Stratego. After a description of currently used techniques a program structure is suggested that combines the use of game knowledge and known algorithms. The document contains a list of improvements that are required to enable more playing strength in a Stratego program. This leads to the conclusion that a lot of research is necessary for the make of a real strong playing program that is based on domain-dependent information.
- Stratego programming and the two squares rule(PDF)
This is a first attempt to define the complex of conditions that determine the capture or non-capture of a piece by enforcement of the two-squares rule. This description enables in move tree search based programs the construction of a look-ahead algorithm that is usable in the evaluation of nodes, quiescence search or forward pruning. The implementation of that kind of static look-ahead probably will lead to a significant improvement of the playing strength and maybe will lead to better behaviour by reducing the amount of senseless chases.
- Stratego programming and initial setups(PDF)
This document contains the results of a study of initial positions. This study covers several subjects:- Simple rules for setups
- Statistics of rank configurations for marshal, general, spy, colonel, flag, bombs
- Statistics of cooperating units of high and low ranks
- Valuation of advices in literature
- Discussion of the choice for a strategy and corresponding setups
- Stratego programming and the static value of ranks(PDF)
This is an attempt to give a theoretical base to static rank values. Literature mentions static rank values but a theoretical base is missing. In this study counts of captures and rank detections in games are transformed to rank values. The results are compared with values in literature. Just for interest an appendix has been added with statistics of games and moves.
A study of the balance of power is now in progress, so that will be the subject of the next downloadable article.
