2000 HiMCM Problem A Bank Robbers

Problem: The First National Bank has just been robbed (the position of the bank on the map is marked).  The clerk pressed the silent alarm to the police station.  The police immediately sent out police cars to establish road blocks at the major street junctions leading out of town.  Additionally, 2 police cars were dispatched to the bank.> >>> Map information:  (see the series of two maps below)> >>> The Bank is located at the corner of 8th Ave. and Colorado Blvd. and is marked with the letter B.  The main exits where the two road blocks are set up are at the intersection of Interstate 70 and Colorado Blvd, and Interstate 70 (past Riverside Drive).  These are marked with a RB1 and RB2 symbol.> >>> Assume the robbers left the bank just before the police cars arrived.  Develop an efficient algorithm for the police cars to sweep the area in order to force the bank robbers (who were fleeing by car) into one of the established road blocks. > > Assume that no cars break down during the chase or run out of gas.> >>> Further assume that the robbers do not decide to flee via other transportation means.

2000 HiMCM Problem B Elections

Problem: It is almost election time and it is time to revisit the electoral vote process. The constitution and its amendments have provided a subjective method for awarding electoral votes to states. Additionally, a state popular vote, no matter how close, awards all electoral votes to the winner of that plurality. Create a mathematical model that is different than the current electoral system. Your model might award fractional amounts of electoral votes or change the methods by which the number of electoral votes are awarded to the states. Carefully describe your model and test its application with the data from the 1992 election. Justify why your model is better than the current model? 1992 Election Summary> >>> State                         Electoral Vote                                Popular Vote> > State> > Clinton> > Bush> > Perot Clinton Bush Perot AL 0 9 0 668146 797477 180209 AK 0 3 0 57264 73683 50034 AZ 0 8 0 521736 543876 339307 AR 6 0 0 495150 331867 97549 CA 54 0 0 4812317 3338942 2144856 CO 8 0 0 625402 557408 362506 CT 8 0 0 681081 574738 348028 DE 3 0 0 125997 102436 59061 DC 3 0 0 186301 19813 9284 FL 0 25 0 2051205 2131263 1040953 GA 13 0 0 1002433 985682 306489 HI 4 0 0 178893 136430 52863 ID 0 4 0 136249 201787 129897 IL 22 0 0 2378873 1717736 832307 IN 0 12 0 839227 978627 451858 IA 7 0 0 583937 503338 251040 KS 0 6 0 386168 443314 312670 KY 8 0 0 661059 617419 203587 LA 9 0 0 815305 729880 210604 ME 4 0 0 261859 207122 205076 MD 10 0 0 941979 671609 271198 MA 12 0 0 1315016 803974 630440 MI 18 0 0 1854603 1585251 819931 MN 10 0 0 994843 734845 549517 MS 0 7 0 391911 478878 83950 MO 11 0 0 1051328 810058 517918 MT 3 0 0 153899 143702 106735 NE 0 5 0 214106 338646 171938 NV 4 0 0 185401 171378 129532 NH 4 0 0 207264 199623 120029 NJ 15 0 0 1361088 1303686 504152 NM 5 0 0 255558 209467 90653 NY 33 0 0 3244562 2240050 1028607 NC 0 14 0 1103716 1122608 353845 ND 0 3 0 97546 133911 69805 OH 21 0 0 1964842 1876445 1024319 OK 0 8 0 473066 592929 319978 OR 7 0 0 524161 393273 307244 PA 23 0 0 2233810 1777372 895563 RI 4 0 0 198877 121864 94717 SC 0 8 0 475313 572031 137598 SD 0 3 0 124861 136671 73297 TN 11 0 0 933618 840897 199787 TX 0 32 0 2278912 2460201 1349644 UT 0 5 0 182590 320462 202578 VT 3 0 0 125803 85512 61510 VA 0 13 0 1033825 1146909 344840 WA 11 0 0 855710 609912 470239 WV 5 0 0 324009 236526 105652 WI 11 0 0 1035942 926245 542610 WY 0 3 0 67863 79558 51209 TOTALS 370 168 0 43682624 38117331 19217213
