Exercise 1 - Data Types
- recapitulate Haskell types (keywords type and data, product and sum types)
- Helium: define equality functions (pattern matching)
- pretty printing
- Define data types that represent boards (Board), squares (Square), positions (Pos), pieces (Piece) and game states (State).
- Helium: Implement suited eq-functions.
- Implement a function prettyBoard::Board->String, that transforms a board into a clearly arranged string representation (human readable :-)). Support this function with auxiliary functions that pretty print pieces, squares, ...
- Define the initial board (initialBoard::Board), test prettyBoard with initialBoard.
- Implement a simple evaluation function evalBoard::Board->Int as the difference of material on board (values: Pawn->1, Knight and Bishop->3, Queen->9, Rook->6, King->"infinity"=1000).
Exercise 2 - Move Generator
Exercise 3 - Gametree Generation and Minimax Algorithm
- break code in modules
- recursive data structures -> recursive algorithms
- Define a data type that represents a game tree.
- Roughly estimate the number of nodes of the gametree with depth 4.
- Define a function play::Gametree->Int, that computes the value of a given game tree using the minimax Algorithm.
