Algorithm

From PIMC++

The algorithm in the input specifies the order in which moves/observables/etc. are called as well as when the data is written.

A typical example of an algorithm is

Section (Algorithm)
{
Section (Loop){ //Start Accumulating observables
int Steps=3000000000;
Section (Loop){
  int Steps=100;
  Section (Move) {string Name="BisectionMoveForHelium";}
  Section (Loop){
    int Steps=10;
    Section (Move) {string Name="Displace";} 
  }
  Section (Move) {string Name="CenterOfMass";}
  Section (Observe) {string Name = "Vacancy"; }
  Section (Observe) {string Name = "PathDump"; }
  Section (Observe) {string Name = "StructureFactor"; }
  Section (Observe) {string Name = "TimeAnalysis"; }
  Section (Observe) {string Name = "CycleCount"; }
  Section (Move) {string Name = "Shift"; }
}
  Section (WriteData){}
 }
}

One basic aspect of the algorithm is the Loop. The only important paramater is Steps: Number of steps that the loop should execute.

The moves and observables are defined by including a Section Move and Observe respectively that includes a single parameter Name that defines the name as used in the definition of the Move and Observable earlier in the input file.

To write out the data, a Section WriteData is included.
