MLDO System State

back

name	type	description	comments
Nsystems	int	#number of systems (DOT instances)
DesignVariables	String[]	values of the design variables for the whole system	maybe it should be double[]
ConstantsValues	String[]	values of the constants sent to DOT	mess: not properly synchronized with lambda, W, and link variables, should be double[]?
ConstantsNames	String[]	names of constants	used for anything?
SubsystemVaraibles	ArrayList<int[]>	mapping between subsystem variables and DesignVariables
link_up	String	value of a link variable	added at hoc
link_down	String	value of the link variable	added at hoc
RouterSlip	String	Router Slip
f,fold	double	used in inner loop
c,cold	double	used in outer loop
tau,beta,gamma	double	used in outer loop
inner_test,outer_test	double	used to test convergence
lambda,W	double	constants	redundant wrt to ConstantsValues
x1,x2	double	used to evaluate f	not general enough
results	ArrayList<String>	array to collects results from each iteration for the final disply

sequence of actions

void setConstantsNumber(int k) void setContantNames(String[] x) void setConstantsValues(String[] x) does debug printout void setConstantValues)double x) void setConstantsValuesV(Vector<String> x) does debug printout Vector<String> getConstantsValues(int s) does debug printout double[] getConstantValues() void updateLinkVariables(int subsystem) void setLinkDown(String s) void setLinkUp(String s)

configuration for each subsystem: configuration::setDot: read constant names values from definition.txt and set configuration variables ConstantsNames, ConstantsValues configuration::setDot: SystemState.setConstantsNumber(ConstantValues.size()); configuration::setDot: SystemState.setConstantsValuesV(ConstantValues); end of configuration dotModule write const.txt (using SystemState.getConstantValues(system) run Dot SystemState.updateSubsystmVariableValues(system, x); SystemState.updateLinkVariables(system); EndInnerLoop SystemState.addResult(); SystemState.converged("INNER") uses tau (hardwired in SystemState) EndOuterLoop SystemState.converged("OUTER") double[] cc.SystemState.getConstantValuesD(); lambda = cc[0] W = cc[1] try { x1=(new Double(link_up)).doubleValue(); x2=(new Double(link_down)).doubleValue(); } catch (Exception e) {System.out.println("conversion error in SystemState.converged 2");} c = x2-x1; lambda=lambda+2*W*W*c; if(Math.abs(c)>gamma*Math.abs(c)) W = beta*W; outer_test=Math.abs(c-cold); cold=c; if(outer_test<tau) result=true; else result=false false; cc[0]=lambda; cc[1]=W SystemState.setConstantValuesD(cc); I think that the problem is that the new values of lambda and W are never written to the consts.txt file. How to make this method generic? Finalizer

RouterSlip

• void setRouterSlip(String s)
• String getRouterSlip()
• String updateRouterSlip(String[] s)

Miscellaneous

• boolean converged(String s) s="INNER" or "OUTER"
• void addResult()
