| 18:18.12 | hippieindamakin8 | yeah his actual name. TOM <smthing> <smthing> Riddle |
| 18:18.13 | hippieindamakin8 | madant_, yeah. |
| 18:18.35 | madant_ | hippieindamakin8, i have a boundary evaluation trouble in libpc :) |
| 18:18.38 | hippieindamakin8 | neways back to the problem i was interested in |
| 18:19.26 | hippieindamakin8 | goes through the source to get into the libpc folder. |
| 18:19.32 | hippieindamakin8 | madant_, tell me |
| 18:20.08 | madant_ | it is about the solver.. while doing the iterations |
| 18:20.24 | madant_ | right now it stores the state of the variables and restores it as a temporary fix :) |
| 18:21.15 | hippieindamakin8 | is going through the pcsolver.cpp |
| 18:21.39 | madant_ | the actual trouble is , if in a list of variables in a constraint network, the first or second variable has the lowest in its domain , it somehow doesn't iterate properly |
| 18:22.03 | madant_ | i mean the trouble is not in pcSolver per se.. must be somewhere in pcVariable* |
| 18:22.22 | hippieindamakin8 | ohk. as in let me understand how this is solving it :| |
| 18:22.42 | madant_ | :) |
| 18:23.35 | hippieindamakin8 | madant_, so u have written this lib or wat ? |
| 18:23.50 | madant_ | yep |
| 18:25.18 | madant_ | hippieindamakin8, sorry, were u asking me to explain the process of solving ? |
| 18:25.27 | hippieindamakin8 | madant_, no :) |
| 18:25.41 | hippieindamakin8 | i am trying to read up the developer doc |
| 18:26.20 | hippieindamakin8 | madant_, i shall get back to u in sometime (shall be going through the doc) |
| 18:28.33 | madant_ | np.. the generic solvers are simple.. it takes the list of all variables, assign a value for each variable in the set, check if the constraints are satisfied , if so adds to the solution, otherwise iterates the variable values continues the process |
| 18:32.49 | hippieindamakin8 | madant_, isnt it libpc that is wat takes care of the p&c .the wiki i guess needs an edit (i am talking abt the proposal /developer doc ) |
| 18:34.55 | madant_ | the developer doc on libpc needs to be updated on a lot of aspects, particularly pcMath* and so on.. |
| 18:35.05 | madant_ | will be doing it before this month end |
| 18:35.38 | madant_ | oh u mean the change from pg to pc .. ah well.. that is there :) |
| 18:36.13 | hippieindamakin8 | madant_, and the doc is very vague :) |
| 18:36.41 | madant_ | yeah it is from the very primitive stage :) |
| 18:37.52 | madant_ | the effective spectrum of parametrics and constraints is pretty large .. :) in fact you have given me a good thought.. i will devote the next few days to making a proper document.. :) |
| 18:37.55 | hippieindamakin8 | madant_, looks like you use c++ builder :) |
| 18:38.08 | madant_ | er ? c++ builder ? |
| 18:38.25 | hippieindamakin8 | i saw this file which includes a .hpp |
| 18:39.47 | madant_ | not sure what u are talking about .. maybe the boost libs ? |
| 18:39.58 | hippieindamakin8 | yeah |
| 18:40.17 | hippieindamakin8 | boost/iterator/............. |

| 19:46.17 | madant_ | i said that ? :O |
| 19:46.55 | hippieindamakin8 | wait you said if they are lowest in the domain :| (and not same) |
| 19:47.57 | madant_ | hippieindamakin8, i mean the trouble happens if in a particular iteration the first variable has the lowest value or something , the following iterations only keep taking into consideration the other variables.. resulting in a loop.. :D and weirdly this happens only if this lowest value in the domain thing happens as the initial state :D |
| 19:48.05 | madant_ | blah.. that was more confusing i suppose :D |
