Development of direct-search strategies in hill-climbing problems
Abstract Hill-climbing problems were presented to undergraduate students to investigate search strategies for finding a maximum point on the surface. Subjects guessed the values of two variables, X and Y, that could result in the maximum value of a criterion variable Z. The function relating X and Y...

| 520 | |a Abstract Hill-climbing problems were presented to undergraduate students to investigate search strategies for finding a maximum point on the surface. Subjects guessed the values of two variables, X and Y, that could result in the maximum value of a criterion variable Z. The function relating X and Y to Z was an inverted paraboloid. Subjects tended to use a systematic strategy in which they adjusted only one variable at a time in order to increase Z. When a failure to increment Z occurred with one variable, they switched to the other variable and adjusted it. Problems in which the paraboloid was highly elliptical were more difficult than ones with spherical paraboloids, especially when the axes of ellipse were not lined up with the X,Y axes. Direct-search strategies are discussed in terms of their efficiency with respect to the number of moves to maximization and cognitive effort. | ||

Development of direct-search strategies in hill-climbing problems |
| abstract |
Abstract Hill-climbing problems were presented to undergraduate students to investigate search strategies for finding a maximum point on the surface. Subjects guessed the values of two variables, X and Y, that could result in the maximum value of a criterion variable Z. The function relating X and Y to Z was an inverted paraboloid. Subjects tended to use a systematic strategy in which they adjusted only one variable at a time in order to increase Z. When a failure to increment Z occurred with one variable, they switched to the other variable and adjusted it. Problems in which the paraboloid was highly elliptical were more difficult than ones with spherical paraboloids, especially when the axes of ellipse were not lined up with the X,Y axes. Direct-search strategies are discussed in terms of their efficiency with respect to the number of moves to maximization and cognitive effort. © The Psychonomic Society, Inc. 1983 |

Subjects guessed the values of two variables, X and Y, that could result in the maximum value of a criterion variable Z. The function relating X and Y to Z was an inverted paraboloid. Subjects tended to use a systematic strategy in which they adjusted only one variable at a time in order to increase Z. When a failure to increment Z occurred with one variable, they switched to the other variable and adjusted it. Problems in which the paraboloid was highly elliptical were more difficult than ones with spherical paraboloids, especially when the axes of ellipse were not lined up with the X,Y axes. Direct-search strategies are discussed in terms of their efficiency with respect to the number of moves to maximization and cognitive effort.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Maximum Point</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Minor Axis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cognitive Effort</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Axis Ratio</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hill Climbing</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Bulletin of the Psychonomic Society</subfield><subfield code="d">Springer-Verlag, 1973</subfield><subfield code="g">21(1983), 6 vom: Juni, Seite 469-472</subfield><subfield code="w">(DE-627)SPR037022717</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:21</subfield><subfield code="g">year:1983</subfield><subfield code="g">number:6</subfield><subfield code="g">month:06</subfield><subfield code="g">pages:469-472</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://dx.doi.org/10.3758/BF03330011</subfield><subfield code="z">lizenzpflichtig</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_SPRINGER</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">21</subfield><subfield code="j">1983</subfield><subfield code="e">6</subfield><subfield code="c">06</subfield><subfield code="h">469-472</subfield></datafield></record></collection>
