Dunn","doi":"10.1137/0317015","DOIUrl":"https://doi.org/10.1137/0317015","url":null,"abstract":"Two conditional gradient algorithms are considered for the problem min ¿F, with ¿ a bounded convex subset of a Banach space. Neither method requires line search; one method needs no Lipschitz constants. Convergence rate estimates are similar in the two cases, and depend critically on the continuity properties of a set valued operator T whose fixed points, ¿, are the extremals of F in ¿. The continuity properties of T at ¿ are determined by the way a(¿) = inf{¿= |y¿¿,||;y-¿||>¿} grows with increasing ¿. It is shown that for convex F and Lipschitz continuous F', the algorithms converge like o(1/n), geometrically, or in finitely many steps, according to whether a(¿)>0 for ¿>0, or a(¿)>A¿2 with A>0, or a(¿)>A¿ with A>0. These three abstract conditions are closely related to established notions of nonsingularity for an important class of optimal control problems with bounded control inputs. The first con-- dition is satisfied (in L1)when meas {t|s(t)=0} =0, where s(¿) is the switching function associated with the extremal control ¿(¿); the second condition is satisfied when s(¿) has finitely many zeros, all simple (typical of the bang-bang extremal); the third condition is satisfied when s(¿) is bounded away from zero. Strong or uniform convexity assumptions are not invoked in the main: convergence theorems. One of the theorems can be extended to a large subclass of quasiconvex functionals F.","PeriodicalId":375119,"journal":{"name":"1978 IEEE Conference on Decision and Control including the 17th Symposium on Adaptive Processes","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122821006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model is applied to behavior in a car simulation and instrumented vehicle. Objective and subjective changes in driver decision making were measured with changes in blood alcohol concentration (BAC). Treatment levels averaged 0.00, 0.10 and 0.14 BAC for a total of 26 male subjects. Data were taken for drivers approaching signal lights at three timing configurations. The correlation between model predictions and behavior was highly significant. In contrast to previous research, analysis indicates that increased BAC results in increased perceptual inconsistency, which is the primary cause of increased risk taking at low probability of success signal lights.","PeriodicalId":375119,"journal":{"name":"1978 IEEE Conference on Decision and Control including the 17th Symposium on Adaptive Processes","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1978-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134159148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
