2.1 The 0-1 Knapsack Problem (KP) The Knapsack Problem is a combinatorial optimization problem‚ which search out a best solution from among many other feasible solutions. It is concerned with a fixed size knapsack that has positive integer capacity (or volume) V. There are n numbers of distinct items that may potentially be placed in the knapsack. Item i has a positive integer capacity(volume) Vi and integer benefit Bi. In addition‚ there are Qi quantity of item i available‚ where quantity Qi is

the dependent variable. This is evidenced by the varying p-values shown in the regression analysis. The null hypothesis for each independent variable states that there is no linear relationship and the corresponding coefficient for the variable is 0. On the other hand‚ the alternate hypothesis states the opposite of the null hypothesis indicating the coefficient of the independent variable is a non-zero value. If the p-value for a particular independent variable is smaller than 0.05‚ we have evidence

The adoption of the AASB 8 has encompassed the transformation from a perspective approach to a management approach to segment reporting. Commentators have contended that the approach places favouritism on preparer’s rather than the users‚ in contrast to its predecessor AASB 114. The favouritism is sourced from the discretion that managers are provided with under the AASB 8. The implementation of the management approach under AASB 8 implies that operating segments identified within internal reports

Archimedes was one of the greatest philosophers who lived from 287 BC to 211 BC in Syracuse. Archimedes was a physicist‚ astronomer‚ engineer and mathematician who discovered and invented machines such as the Archimedean screw‚ Archimedes principle‚ Archimedean spiral‚ Archimedes claw‚ planetarium‚ compound pulley system and many war machines. His greatest contributions were in geometry and his methods and ideas started the idea of calculus and finding the density of an object without damaging the
