GLOBALLib Changelog =================== 2/9/15: ------- For the model flowchan of the GAMS model library, a bug in the specification of boundary conditions has been discovered and fixed in the model library of GAMS version 24.4. Essentially, this leads to a change in the right-hand-side of one constraint (from 0 to 1). Accordingly, we added fixed variants of the flowchan instances to GlobalLib: flowchan50fix.gms flowchan100fix.gms flowchan200fix.gms flowchan400fix.gms The previous instances are still available (under their original name). 2/19/13: -------- A number of duplicates has been identified: ex9_2_1 is the same as ex9_2_7 ex9_1_10 is the same as ex9_1_8 ex8_1_8 is the same as st_e20 gangesx is the same as ganges gancnsx is the same as gancns himmel11 is the same as st_e28 pinene25 is the same as pinene50 prob05 is the same as st_e08 st_bpk2 is the same as st_bpk1 st_e10 is the same as ex4_1_8 st_e20 is the same as ex7_2_2 st_e39 is the same as ex8_1_6 st_fp1 is the same as ex2_1_1 st_fp2 is the same as ex2_1_2 st_fp3 is the same as ex2_1_3 st_fp4 is the same as ex2_1_4 st_fp5 is the same as ex2_1_5 st_fp6 is the same as ex2_1_6 st_jcbpafex is the same as st_e23 st_kr is the same as st_phex st_pan2 is the same as ex2_1_1 For each pair, the first instance has been removed from the library. 4/20/04: --------- Converted optimization direction from max to min for the models listed below. Note that the objective sign will differ for these models from the previous. All models in GLOBALLib are now minimization problems. arki0003.gms arki0007.gms arki0009.gms arki0010.gms arki0011.gms arki0012.gms arki0013.gms arki0014.gms arki0015.gms arki0019.gms arki0020.gms arki0021.gms arki0022.gms arki0023.gms arki0024.gms btest14.gms glider100.gms glider200.gms glider400.gms infeas1.gms maxmin.gms polygon75.gms 12/11/03: --------- Added new GAMS Software GmbH client model gsg_0001.gms GAMS Software GmbH family of models will be prefixed by gsg_. 09/03/02: --------- Added new group of GAMS Models. Model names have prefix st_(model).gms 08/23/02: --------- Added new group of GAMS Dev. Client models. Fixed minor bugs in some model pages. 07/31/01: --------- Beta version of the GLOBALLib published on hidden web pages with 256 models. Library consists of the model from Floudas et. al. Handbook of Test Problems and models from the GAMS Model Library. 07/16/01: --------- Alpha version of the GLOBALLib published on hidden web pages with 109 models. MAINTENANCE INFORMATION FOR WEBMASTER ===================================== Adding New Models To GLOBALLib: ------------------------------- The following needs to be updated in globallib.gms: 1. Update set s sequence number to reflect additional number of models 2. Add models to the set m models with their URL source 3. Update set ms(m,s) model sequence mapping to include new models 4. If necessary, update set ds(d,s) model application mapping 5. Add reference mapping from globallib.gms internal to gams.bib external reference map. This should look something like: $echo r166 37 >> g2g.txt where r166 is the globallib.gms internal reference number and 37 is the gams.bib reference number. REMARK: The files gams.bib and bib2gms.exe need to be in the same directory as all globallib.gms files. When globallib.gms is run, the reference file globalref.inc is automatically updated to include the new references. 6. Update model reference mapping set mr(m,r) 7. If solution points exist, update set mp(m,p) available restart or solution points, as well as set bk(m,p) point with best known solution. Once this is completed, proceed with the following: 1. Add new models and solution points to globallib.zip 2. Freshen globallib.zip: >> gmszip -f globallib.zip 3. Run globalstat.gms: >> gams globalstat.gms 4. Run globalhtm.gms: >> gams globalhtm.gms
