The Watchmaker

July 24, 2011 by Eric Marcarelli in Poems, Writing 0 comments
I’ve uncovered a lost character from the Canterbury Tales: A watchmaker was anachronistically there, His bent back and crooked hands his sins to bear. He carried the tools of his wicked trade, The masters of men he slavishly made. No longer a dial, a candle, a glass; Banish the sun and moon alas. Equal hours were his dark art, Crafting time as empty as his heart. The Prince of Darkness beside him as he rode, A pilgrimage was his hope’s last abode.

Xovos: Web Design through Evolution

August 08, 2010 by Eric Marcarelli in Projects, Technology 0 comments
Xovos is the senior project I completed last May. It is a program that develops web designs in an evolutionary environment with user interactions and preferences as the selection criteria. The project consists of five basic parts. The user interface allows the user to interact with the program. A set of genes makes up a chromosome that describes a design. An offspring generator mates the designs from the current generation to form the next generation. The design generator parses the design chromosomes to create the visual representations of the design. Finally, environmental preferences (also called monsters) allow users to set basic criteria for designs that will be automatically selected against. In my research I have not been able to find anyone else who has tried to apply evolutionary programming to web design in this way. The closest related work is on evolving programs that are designed for specific tasks and are not visually oriented.

The Stone Wall at Tagamore Swamp

August 08, 2010 by Eric Marcarelli in Nature, Poems, Writing 0 comments
No tame trail leads one there Through wild rye and tangled brier, Over paths unworn, To the old stone wall That weathers all. A remnant of lost triumph; The artifact of forgotten struggle. When leaves ate wood And thatch wore to soil, Crops to seed, And stock to feral, It stood there still: The old stone wall That weathers all.

A Fair Game of Blackjack between Two Players

August 08, 2010 by Eric Marcarelli in Projects, Technology 0 comments
It is possible for two players to use cryptographic techniques to play a fair game of Blackjack without having to trust the other player or use a trusted intermediary. The cards a player receives are random and at the end of the game both players are able to confirm that the other player’s score accurately reflects the other player’s cards. I will begin with a general discussion of the technique, then move into an examination of the program that implements it. Logs from an example game and the code for the project are included at the end.

Chess AI Project

August 08, 2010 by Eric Marcarelli in Projects, Technology 0 comments
The Chess AI program I wrote is capable of playing through a full game of chess. The human player takes the side of white, and the computer will respond with black’s moves. The game can look an arbitrary number of moves (plies) into the future to select the best move. It uses four plies by default and takes between 10 and 90 seconds to make a move depending on the complexity of the current position. The game is written in C++ using SDL for graphics.
