Particulars of physical experiments (10 trials each)

• Photos of initial condition and final condition
• Assembly of one target structure
  • Data to be collected: number of targets and number of incompatible substructures, time for steady state
• Assembly of two target structures
  • Data to be collected: number of targets and number of incompatible substructures, time for steady state
• Assembly of three target structures
  • Data to be collected: number of targets and number of incompatible substructures, time for steady state
• Assembly of four target structures
  • Data to be collected: number of targets and number of incompatible substructures, time for steady state

• Results to show
  • The simulated probability of the formation of 1, 2, 3, 4 and 5 target structures in self-assembly experiments
  • Comparison of simulated probability vs. probability achieved in physical experiments
  • Reasons for similarities and/or differences between simulated probability vs. probability of physical experiments
