1 Exercise 1 - Data Types

1.1 Learning Targets

  • recapitulate Haskell types (keywords type and data, product and sum types)
  • Helium: define equality functions (pattern matching)
  • pretty printing

1.2 Tasks

  • Define data types that represent boards, squares, positions, pieces and game states.
  • Helium: Implement suited eq-functions.
  • Implement a function prettyBoard, that transforms a board into a clearly arranged string representation (human readable :-)). Support this function with auxiliary functions that pretty print pieces, squares, ...
  • Define an initialBoard, 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")

2 Exercise 2 - Move Generator


3 Exercise 3 - Gametree Generation and Minimax Algorithm

3.1 Tasks

  • 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
  • pretty printing
