How to use

1. Run ListFile. You will be presented with a Directory Tree on the left, and an empty Table with headers on the right hand side.
2. Drag folders from the Tree on to the Table. All files in the folder will be tabulated against the Table header (eg file attributes such as filename, directory etc). There are more than 2 dozen attributes to choose from.
3. Left Click on Table headers to sort.
4. Right click on Table headers separator to insert file attributes from the Table.
5. Query the Table and generate a second Table, based on file attributes or file contents specified in the query. Use and/or logic to construct complex queries. A query may be set as a filter. Any folder dragged from Tree to the Table will be filtered accordingly.
6. Copy files listed in a Table to a folder.
7. Export a Table to an Access, Excel, CSV or HTML file, or to ZIP file.
8. Many more options.

Updated 28 July 2004

Main purpose of this program is to make abstract patterns from a subset of an image. Patterns are beautiful to observe and interesting to analyze. However, what makes a pattern look good is a mystery. Certainly some kind of ordered repetition appears pleasing to eye. The pattern making replicates parts of an image in an organized manner. Even with just using a few of the numerous ways of arranging an image, the results appear pleasing and delightful. A pattern can then be manipulated through filters and special effects for added abstraction.

Filters and special effects can be used on standard image files also.

version 1.0
Updated 21 July 2004

Two-player, strategy game Abalone was invented in 1990 by Laurent Levi and Michel Lalet. The concept of the game is based on the popular Japanese Sumo wrestling.

Layout

The board is a hexagonal field representing the Sumo arena. There are 4 interlaced different size hexagons, where the most exterior hexagon has 5 circular locations at each side. In the middle there is a single location. As a total, there are 61 circular board locations. Each player has fourteen pieces that can rest in these locations. In initial game position Green pieces are at the top three rows, and Red is at bottom three rows.

Start

Starting from the initial configuration, each player takes a turn. During a turn, a player can shift one, two, or three pieces together in any of the six directions, provided that there is an adjacent space, i.e., in line or broadside. Furthermore, whenever a player has a numerical superiority in a line (three to two, three to one, or two to one), during a turn the player is allowed to push the opposing marbles with an inline move.

Aim

Players take turns "pushing" 1, 2 or 3 linearly connected pieces, attempting to push their opponents' pieces off the board. First player to push 6 of their opponent's pieces off the board wins. One of the players can be the computer.

For detailed instructions and strategies for play see numerous Abalone sites on the Web.

A simple game, yet of surprising mathematical subtlety. Complete your chain before computer does.

Layout

Hex is played on a diamond-shaped board made up of hexagons. The number of hexagons may vary, but the board usually has 11 on each edge. Two top and bottom opposite sides of the diamond are labeled red, while the hexagons at the left side and right side are green. One player plays with green pieces while other with red. The players alternatively place one of their pieces on any one of the hexagons, provided the cell is not already occupied by another piece.

Aim

The objective of the Hex game is to complete an unbroken chain of green pieces between the left side and the right side. While red tries to complete a similar chain of red pieces between the top side and the bottom side.

The chain may freely twist and turn. The players continue placing their pieces until one of them has made a complete chain. The game cannot end in a draw, because one player can block the other only by completing its own chain. These rules are simple, yet HEX is a game of surprising mathematical subtlety.

How to play

In this computer game, computer always plays red. Green usually starts first unless overridden. Left-click in a cell to place a green place. If you wish computer to start first, right-click on any cell on the board.

20,000 puzzles of different difficulty levels

Cardoku is a Sudoku look alike with some subtle differences. This puzzle has following rules:

1. A puzzle has a 7x7 grid and a 52-card deck. A puzzle and its solution use only 49 cards.
2. Some cards are already placed on the grid as part of the puzzle. The remaining cards are stacked for use.
3. You are required to place all the remaining cards on the grid, given the following rules:
   • No duplicate numbers in any row or a column
   • A cell cannot have a card suite of the neighboring cells. Neighboring cells are Up,Down,Left and Right.
   • A cell cannot have neighboring numbers of the neighboring cells. Neighboring numbers are +1 and -1 of a number. For example neighboring numbers of 5 would be 4 and 6; neighboring numbers of 1 will be 2 and K, and neighbors of K will be 1 and Q.
     
   • Consider:
        5C
     3D ? 1H
        KD
     Cell in the centre has to be a Spade, and its value cannot be 2,4, 4,6, 2,K, and 1,Q. Also 3,5,1,K cannot be placed being in the same row and column. Therefore this cell cannot have 1,2,3,4,5,6,Q,K. In this case if only 7 is left in the remaining spades, then 7S must be placed in this cell.

A magic square is an arrangement of the numbers from 1 to n^2 (n-squared) in an nxn matrix, with each number occurring exactly once, and such that the sum of the entries of any row, any column, or any main diagonal is the same. It is not hard to show that this sum must be n(n^2+1)/2.

Sometimes the magic squares above are called 'normal' squares, where cells are filled with numbers 1 to n for a grid of size n. Another set of magic squares is where a cell may be filled with any number, with the sum of rows, columns and diagonals being a pre-selected number.

This program computes 'normal' as well as the 'variable' types of magic squares. Following options are provided:

• Grid Size can be 3 to 50. Note that larger grid sizes will take a long time to solve
• Solve - Auto, computer will calculate the MagicSquare. For variable magic squares, the program uses a combination of random guesses and solution of equations in order to arrive at a solution quickly. Each variable magic square solution is likely to be different. For normal squares a combination of La Loubere and LUX methods are used
• Solve - Manual, a blank grid is presented for user to enter numbers in the grid and solve the puzzle. Right click on a cell to a get drop-down menu for manipulating cell values
• Print - Print the solution and the empty grid for attempting solution on paper. Maximum grid Size that can be printed is 30

The purpose of this challenging game is to make a number from a set of six numbers.

The computer selects the number that you are required to make along with six other numbers. You select any two numbers and apply addition, subtraction, multiplication or division to get an answer. This answer is added to the set of remaining numbers. You repeat this process until the desired answer is obtained.

In order to make 468 from 1,22,34,7,13,25 one solution would be:

1. 7 + 13 = 20
2. 25 - 1 = 24
3. 20 * 24 = 480
4. 480 + 22 = 502
5. 502 - 34 = 468

Note that you may use a number only once. You may use the required number for intermediate calculations. In order to select a number click left-mouse-button on the number Click on + - / or * for mathematical operations. All six numbers must be used for the target.

Introduction
This program is a simple game using a board layout based on Nash equilibrium (named after John Forbes Nash, who proposed it). This game is not about demonstrating the equilibrium theory or its application. Nevertheless some principles of the equilibrium theory would apply when you play this game against the computer.

Board Layout
A 3x3 matrix contains nine numbers distributed randomly. Player 1 has numbers 1 to 9 in the bottom left while player 2 numbers 1 to 9 are in the to right corner of a cell.

Objective of the Game
Players 1 and 2 move alternatively. Purpose of this game is for a player to maximise its score.

How to Play

1. Player 1 start first by selecting a one of the three rows
2. Once a row is selected, player 2 must select a column in that row
3. Player 2 then selects a column:
   • If player 2 selects same column as the row number (eg column 3 if row 3 was selected by player 1) then the respective numbers in the common row/column are added to player scores and game ends
   • If player 2 selects a column (eg column 1 in row 2 selected by player 1), numbers at the intersection row and column are added to player scores
   • Game continues and player 1 selects another row - then step 2 above follows ...

Program Options

1. Select player types: manual or computer. User can play player 1 or 2 but player 1 always starts the game
2. Select how a game ends:
   • When same row/column are selected (default and normal mode)
   • When only one cell is left. This game would last longer.
3. Board and player colours
