haive.games.reversi.models

Comprehensive data models for Reversi (Othello) strategic board game.

This module defines the complete set of data structures for the classic Reversi game, providing models for move validation, strategic analysis, and board position evaluation. The implementation supports standard 8x8 Reversi with traditional disc-flipping mechanics.

Reversi is a strategic board game involving: - 8x8 board with alternating black and white disc placement - Disc-flipping mechanics with line capture rules - Strategic corner and edge control - Endgame optimization for maximum disc count

Key Models:

Position: Board coordinate representation (row, col) ReversiMove: Player’s disc placement action ReversiAnalysis: Strategic evaluation for AI decision-making

Examples

Working with positions:

from haive.games.reversi.models import Position

# Corner positions (strategic)
corner = Position(row=0, col=0)
opposite_corner = Position(row=7, col=7)

# Center positions (opening)
center = Position(row=3, col=3)
adjacent = Position(row=4, col=4)

Making moves:

from haive.games.reversi.models import ReversiMove

# Black player opening move
move = ReversiMove(row=3, col=2, player="B")

# White player response
counter_move = ReversiMove(row=2, col=2, player="W")

Strategic analysis:

from haive.games.reversi.models import ReversiAnalysis

analysis = ReversiAnalysis(
    mobility=12,
    stability=8,
    corner_control=2,
    edge_control=5,
    evaluation_score=0.3,
    strategy="Focus on corner control and edge stability"
)

The models provide comprehensive strategic analysis capabilities for AI-driven Reversi gameplay with position evaluation and move optimization.

Classes

Position	A coordinate on the Reversi board.
ReversiAnalysis	Strategy and evaluation report for a Reversi position.
ReversiMove	Represents a single Reversi move.

Module Contents

class haive.games.reversi.models.Position(/, **data)

Bases: pydantic.BaseModel

A coordinate on the Reversi board.

Parameters:

data (Any)

row

Row index (0-7).

Type:

int

col

Column index (0-7).

Type:

int

Create a new model by parsing and validating input data from keyword arguments.

Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.

self is explicitly positional-only to allow self as a field name.

Type:

str

Create a new model by parsing and validating input data from keyword arguments.

Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.
