Electronic Brain Computes Difficult Problems uIcdy Inventors of MITAB (Mechani- cal Transportation and Assign- ment Blackboard) say this device provides 20-minute answers to problems larger electronic compu- ters would take years to do the "long way around." MITAB was designed and built by mathematicians and engineers in the Operations Research group of the University's Engineering Research Institute for a bargain price of $5,000. It is described as a mechanical blackboard that "erases itself" au- tomatically but can restore the problem as it was originally set up if the operator wishes. "Forgets" Instructions Not a computer because it can- not remember instructions, it can only add, subtract and perform other "simple" functions as finding the best of two billion billion pos- sible answers to a specific problem. It was built by suggestion of Merrill M. Flood, associate director of ERI. James Munkres devised a set of rules by which the machine may solve a class of problems effi- ciently and rapidly. Actual construction was done by engineers Bruce Weinert, Harold Sherman .and Joseph Hoagbin, mostly in their spare time, with second hand equipment. Building funds were supplied by the Engi- neering Research Institute. According to Robert Machol, ERI systems engineer, the ma-{ chine has potential as a research and instructional tool. Its solu- tion methods can be adapted to make conventional computers even -more efficient. MITAB has a great face con- taining 400 indicators, 400 switch- es and 800 lights. The indicators are in twenty rows and columns, solving a variety of combination- permutation problems. For instance, if 20 men had to do 20 jobs, and the rows represent men and the columns, jobs; then the machine can compute the number of ways a business man- ager can assign jobs (2,432,902,- 008,176,640,000). T h e problem which the machine solves is finding the best arrangement, using the business manager's criteria-least total cost and 'fastest operating time. Performs Tricks It scan perform mathematical tricks with its rows and columns, solving problems in minutes that a high speed computer would take years to do. However, if the high speed com- puter is "shown the way" by MI- TAB it could solve the problem in seconds. By DAVID TARR Underlying the border dispute between the Central American countries of Honduras and Nicara- gua is a jungle-land area thought to contain oil. This natural resource caused fighting this week and has resulted in the two countries' going before the Council of the Organization of American States, even though the land dispute has been simmering for some time. Both Nicaragua and Honduras had claimed the area for many years before 1906 when King Al- phonso. XIII of Spain awarded it to the latter. Ruling Unrecognized Nicaragua does not recognize that arbitrary ruling, but claims the Spanish king had no legal jur- isdiction to award it to Honduras, and claims the area as her own. Some fighting has occurred dur- ing the week but inadequate and conflicting reports make the situa- tion today unclear. Both countries seem prepared to accept arbitration before the OSA now that it has established a five- man investigating committee. This group has been sent to the troubled arera, Both countries have charged each other with aggression before the OSA Council. Honduras sent a note Tuesday claiming Nicara- gua had invaded the territory awarded her (Honduras) in 1906. Honduras is reported to have be- gun her move to expel Nicaraguans from the disputed area Wednesday by capturing the small town of Mocoron. This prompted Nicaragua to brand Honduras the aggressor. Intervention Asked Both nations have asked inter- vontion under the Western Hemis- phere's collective security pact. On Friday, Honduras asked invocation of the Rio Pact, which allows col- lective a c t i o n and sanctions against hemisphere aggressors. .O*A's Council decided the Pact should be invoked although this requires a meeting of foreign min- isters of member nations. The five-man committee estab- lished to investigate the trouble is intended, in part, to provide a "cooling off" period between the states, a method which has been used in the past. The collectivei4 security pact among the 21 American republics is now in its 10th year. It was last used to prevent war in 1954. j STATUUt Af HONDURAS D d Terato NICARAGUA anaqu~a COSTA RKCA ' DISPUTED AREA ... oil resources DAILY OFFICIAL BULLETIN (Continued from Page 4) Science Research Club, May meeting in the Rackham Amphitheatre at 7:30 p.m. on Tues,, May 7.
