*A '''variable''' is simply a letter of the alphabet (e.g. A) that comes in two types called literals -- a and a'.  Note:  Alternative notations could be A and a, or (a) and (not a).
 +
*A '''clause''' is made up of two or more literals with the logical operator OR between (e.g.  (a OR b') is a clause.) 
 +
*A '''SAT problem''' in conjunctive normal form is comprised of two or more clauses with the logical operator AND between.  The number of literals in each clause is the value of k in our use of k-SAT to describe a problem. 
 +
*An '''input''' is an assignment of one of the corresponding literals to each of the variables.  For example, (a, b' c') is one of eight possible inputs in a 3-variable problem.

Vocabulary:

  • A variable is simply a letter of the alphabet (e.g. A) that comes in two types called literals -- a and a'. Note: Alternative notations could be A and a, or (a) and (not a).
  • A clause is made up of two or more literals with the logical operator OR between (e.g. (a OR b') is a clause.)
  • A SAT problem in conjunctive normal form is comprised of two or more clauses with the logical operator AND between. The number of literals in each clause is the value of k in our use of k-SAT to describe a problem.
  • An input is an assignment of one of the corresponding literals to each of the variables. For example, (a, b' c') is one of eight possible inputs in a 3-variable problem.

Examples:
(a OR b') AND (a' OR b') AND (a OR b) is a 2-variable, 2-SAT problem with 3 clauses using 4 literals.
(a OR b OR c) AND (a' OR b OR d) AND (a OR b' OR d') is a 4-variable, 3-SAT problem with 3 clauses using 7 literals.

  1. The question of interest for a SAT problem is whether or not there exists an input that makes the overall logical expression true.
  2. The question of interest for a MAX SAT problem is to determine the maximum number of clauses satisfied when considered over the set of all possible inputs.


Biology Based:

  1. Which reporters are we going to use?
  2. What naming system are we going to use for the suppressor tRNAs?
  3. How do you build the tRNA construct?
  4. How are we going to build the 5-mer BioBricks?

Math Based: (Davidson) We have posted a Mathematica notebook on the Wiggio. Basically we are at a point where we can choose the number of variables, SAT number(2-SAT, 3-SAT, etc), and the number of clauses to use at a time and produce a table of inputs as the rows and clauses as the columns, with a 1 if the input satisfies the clause and a 0 if the input fails to satisfy the clause. In addition, we can produce a "Super Table," which lists all the SAT problems given the number of clauses in conjunctive normal form and displays how many of the clauses in a given problem each input satisfies. Feel free to view the posted Mathematica notebook; there are some instructions within the notebook itself. When you open it, there will be a window which asks about dynamic content; be sure to click "Enable Dynamic."
