S i bugs is an explo a ion o li e algo i hmic con ol in co pus-based pe o mance. A communi y o compu a ional
agen s con ined o a wo-dimensional squa e p ison cell is li e-coded in o collec i e madness.
Agen s a e con olled by simple code unc ions ha de ine na iga ion in a e ain made o a collec ion o elec onic
noise samples. Each agen is also associa ed wi h a sound playback/syn hesis unc ion. The pe o mance emb aces he
complexi y eme ging om quickly coding a mul iplici y o beha iou s in a sha ed sonic space.
2 PROJECT DESCRIPTION
In p e ious wo k [

] a amewo k o he isualiza ion o sound collec ions was p esen ed, including an implemen a ion
in he Supe Collide language
1
. This allows o ep esen ing a sound co pus as a 2D g id which is compu ed h ough
audio analysis and dimensionali y educ ion. Each indi idual sound is ep esen ed as an icon which shows he empo al
e olu ion o loudness and spec al cen oid. The isualiza ion can hen be used o co pus-based composi ion and
pe o mance [4].
One way o na iga e he co pus is by using li e coded a i icial agen s. This app oach, inspi ed by agen -based
modelling [

,

], can be desc ibed as agen -based music li e coding (ABMLC). The concep ual model and implemen a ion
a e explained in mo e de ail in [

]. Each agen is de ined by a sho code snippe which con ols he posi ion in he
isualiza ion. Se e al unc ions, such as pa e ns, lines, andom walks and o bi s a e explo ed. The isual anima ion
imp o es he eadabili y o he pe o mance wi h espec o he aw code.

is a bespoke li e coding en i onmen w i en in Supe Collide , which allows li e coding o isual agen s on a
2D su ace. The e ain (da a a ailable o agen s in he sha ed space) may be gene a ed in di e en ways, including he
isualiza ion o a sound co pus. Each agen is li e-coded h ough i s co esponding ex box in plain Supe Collide
language. An agen is also associa ed wi h one o se e al syn h de ini ions which ha e been coded in ad ance. In
