Using Computation to Self-Assemble Patterns

Self-assembly is the process during which a collection of relatively simple components, starting in a disorganized state, autonomously combine into a more complex structure. During self-assembly, there is no external guidance or direction, and the self-assembling components experience only local interactions and typically obey a simple set of rules that govern how they combine. We…Continue Reading Using Computation to Self-Assemble Patterns
