Let’s say I have a set of equations I want to solve.
I use Solve[.] and get a non-unique solution.
Can I restrict the solution values to integer values?
I know it can be done in NMinimise[.] or Minimize[.] For example {p,n,d,q} -Element of- Integers. Alternatively, can I specify that the solution values must come from a set of integers from 1 to 16?
As a backup I guess I could just reformulate my problem to minimise the deviations from equality and then use NMinimise[.] or Minimise[.]. I have a genetic algorithm firing away in the background at the moment (through excel) at the rate of 450,000 trials per hour. Any idea how fast NMinimise is by comparison?
The specific problem I’m working on has 2*10^13 possible combinations.
